Whats Wrong With My Plants?


Recommended Posts

Hi. Recently i set up a drain to waste system. BC aka technaflora nutrients. Im using the equivalent of 3tsp bc boost and 3 tsp bc bloom per gallon, in a 55 gallon drum. Im using promix HP but next grow will be switching to coco coir.

 

Anyways im growing hindu kush and vannila kush. The hindu kush plants look killer. But while the buds at 4 weeks on the vannila kush plants look good, the leaves are looking BAD.

Here is a pic. The bigger leave was taken near the bottom of a cola and is just starting to show problems, and the smaller leave which came from higher up on the cola is totally hit.

Any ideas?

Fyi im running well water from my own well so it shouldnt be lacking any micro nutrients.

I am no expert at this, I have only found ways around it. I have owned 2 different properties, each with a well. Both wells had big differences in pH and ppm. Both caused much havok and I learned to go around it. Especially for each individual strain. Too much ppm of one mineral can prevent the uptake of a nutrient. With a well, the ppm must be known. I have always used rain water. To avoid problems like you are showing, I transplanted into oversized buckets. I have no experience with hydro. The rainwater I consider to be useable ranges about 20 ppm. Anything above that I will not use it. Currently my well water only reads just over 200 ppm with a 6.9 - 7.0 pH which is pretty good for a well, but still causes problems with some of my strains. When I am forced to use my well water I will only use it if it has ran through my RO filter. Then I can up the ppm with the exact nutrients I want. Flushing it with your well water could make it worse. You may want to flush it with RO filterd water or distilled water and treat the water appropriately with nutrients after flushing. Again, I never mastered the nutrients, just leaned ways to get around it. I always prefer rain water when I can get good, clean rainwater. This is with respect to soil organic growing. I highly recommend you invest in a TDS meter or ppm tester. You will probably need to also invest in an RO filter. This is the one I have http://www.freedrinkingwater.com/ro-counter-detail.htmI could only get it to hook up to my bathroom sink, but it works. All we drink is RO filtered well water.

well water will not necessarily provide all of the "micronutrients" needed for thought, but your nutrient choice does. If you aadding anything over and above your nutrient line will not "fix" the ph problem, or the deficiency you may be having at this time, while following directions on the bottles, a ph issue is the first thought, prohibiting proper uptake of the nutrients being supplied.

 

atmosphere-check

nutrients-check

ph- check

water quality- check

nutrient ppm's-check

 

 

carefully clip those ugly leaves off first......pests love weak leaves showing issues.

 

 

you'll be fine, might just be a particular strain bucking your system, show her who's boss..!

Use real soil. No ph required. I pull from the tap and it goes straight to the plants. Only volume is measured.

 

Obviously that is extreme, but once I made the switch I haven't (and won't ever) look back. Vanilla kush (assuming barney's) was the weakest plant I have ever had from barney. I loved the flavor but 10/10 were deemed unfit for my purposes.

it is NOT light burn btw.

 

clip the unhealthy leaves, stop the nutrients for a couple days, check your ph in/out with a meter.fresh batteries.  I'll gift you a ph meter, if you buy me lunch....but really, I think you'd save cash on amazoncom  buying the meter....but I will give you one if you want it.

 

I remember my hydro days....back when I couldn't decide if I was a tinkering mopper, a wet/dry vac mechanic, or just loved high humidity, electronic meters, over priced bottled farm nutrients/chelated macro's. I grew in dirt once, with rabbit chit only, and stacked 100% of my hydro supplies in the rafters. never looked back(or up), and would highly rec growing in quality soil. Your well water will make you a star growing in dirt. 11 bucks will get you a quality report from the dnr, ppm's, arsenic, mercury, lead, benzene etc......for a better night sleep.  one step up would be an octopot, then you can at least pretend you're a tinkerer, removing the boredom of dirt growing.

 

my mop head dried out, my wet/dry vac broke, and every fitting, glue, hose clamp, tool, is now out of the room! for good! 

 

I'll see you on the other side....soon I bet :jig:

Its not really hydro. Im growing in promix, which ive done for years with no problems, only ive rigged up an automatic watering system that could be considered drain to waste.

I just dont get why im getting these problems now. Really nothing had changed except the that the plants are getting wateres with a pump instead of by hand.

 

I have a ph meter. My tap ph is 7.14, ive dropped it down to 6.2 and cut the fertilizer in half for this next feeding. I will be getting a ppm meter, would like a RO system bum im not crazy about how much water it wastes

yeah, I agree about the RO systems.

 

maybe you just have some anomaly punk plant this time around?  If her clones report this way in flower I'd cull her. I like non fussy pets in my garden. on the other hand some growers love to take care of the needy and do well at it.

 

not that it applies but I once re-plumbed a room with a top feed system. I ran out of the "black" tubing I bought, specifically for watering btw, and found a deal on dark blue pure silicone tubing online and finished up with that. If that didn't happen I wouldn't have noticed a severe plant issue in EVERY plant plumbed with the "black" tubing....I freaked out!  removed them all at once and used silicone replacements, flushed plants with water for days, changed out the res twice and back to normal...what a bummer though....I have no idea what the issue is/was, but the grow store changed their supplier and said nobody liked the black tubing. They changed to "drinking water safe" hoses. I suspect the others were too, but made in china........ :mad: :sick:I later found they made water very acidic.

Im not using cal/mag cuz im using well water and the water is pretty hard though ive never had it messured, but it leaves calcium all iver my dishes.

 

The problem im noticing is that everyone has their own opinion, and i respect and appreciate each of them.

RO water?

Phosphorus defeciency?

PH problem?

Nutrient burn?

Light burn?

I dont know what to do at this point.

I havent watered yet and wont till tomorrow.

Ive raised my lights almost to the cieling. Ive ph adjusted the water.

Now im not sure if i should flush with water if its overfertilized or do as the growshop guy suggested and add a bloom booster.

I think im gonna half the dose for the next couple waterings.

theres not one perfect method everyone uses.

 

some people use well water, some dont.

some people use hydro, some use dirt, some soilless.

 

all we can do is come up with generic solutions to common problems.

 

heat problem- monitor temps and keep plants between 75-85F

light problem- hold your hand on top of your plants, if your hand starts burning it is too close to the light.

ph problem- calmag/epsom salts sometimes helps. flushing sometimes helps. filters sometimes help.

nute problem- cutting back on feeding solves a lot of problems. flushing can also help.

water problem- having your water tested is always a good idea, especially if you are also drinking it.

 

 

you also have to take into account that hydro store employees are there to sell you products. note that most of the above common suggestions requires no money. epsom salt is pretty cheap.

 

aha, i have one more suggestion.

is it overwatered? how wet is the soil? how often are you watering? overwatering can cause ph problems, lockout etc.

I cant really tell by the couple of leaves. But I will simply give you the top 3 things it almost always is:

 

1) pests

2) ph burn/fluctuation

3) Nutrient burn

 

Either something alive is causing the spots, or something is gathering in too large a quantity at the wrong ph and causing the burn spots.

Yes, absolutely 100% correct in that the biggest problem when it comes to reasoning through advice is figuring out which info is correct and applicable. Absolutely the biggest problem w online forums, especially considering that many false claims grt repeated and repeated and repeated to the point that they become part of 'conventional wisdom', and effectively 'true'... Even though you really need to do the exact opposite.

 

You dont know me for anything, so this is easily dismissed, and i have no skin in your game so it wont hurt my feelings if u do so. I really dont like to ever comment anymore on advice, but what you posted brought about some sympathy... So here ya go, contrary to what conventional advice suggests...

 

The reason the upper and mid fan leaves are most affected is because they are closest to the light and quite reasonably use more nutes than parts of the plants farther from the light. This means you should:

- reduce light intensity... back the lights off, and for the next grow, better regulate your canopy so u have fewer colas that overstretch the rest of the plant body

- increase available (and needed) nutes... By upping your nute load, or increasing your feed rates. You need more K and Mg in particular.

- higher heat adds to the cycle you r in.

 

You may havr other issues, entirely possible, very tough to give advice on w/o being there and really knowing what u have been doing. But backing off your nutes and flushing w water will make the die off worse, though raising your lights def will help (as u have done).

 

Get an ec meter and check ur runoff rates, otherwise u r trying to diagnose while missing a big chunk of info. Same w the ph. Same w ur feed rate/frequency info, coupled to ur actual and real conditions within the room.

 

But the basic problem is simple enough... The leaves tell u they r hungry for usable nutes. Why that is? U dont enough total info for anyone to acurately say, but what u have posted and prev experience points to light intenisty and not having sufficient macros, esp K and Mg.

 

Id want ur runoff ec and ph to b more comfortable in suggesting, but id bet a cnote in the dark they need more food. How u do that, depends.

Btw... Light intesity and higher demand for macros isnt the same as light burn. Ur pic is definitely not light burn, so stop thinking about that. They r hungry, and that is what u need to figure out.

 

Flushing (conventional wisdom), is more than likely wrong. U will only exacerbate the problem. If u flush, it should b w full strenght nutes and w a super high volume to balance your source feed w ur runoff... But without an ec meter you can not do that... U have less than half the info nec to diagnose or use specific recommendations. Same w the ph.

 

And add 1.5 tsp of epsom salts per 5gal to stall the spotting, maybe hit them w a one time 3tsp per 5gal of epsom and then use the 1.5tsp every feed thereafter.

looks like potassium deficiency.

more probably its just nute burn. give it a flush or two of water and only feed it every other time, you can always underfeed but no help for overfeeding.

could also be ph problem like willy says.

great find!  great pics!!  i gotta print and post on grow room walls.  I am seeing a phosphorous def outdoors on one of the herd, an afghan kush with dark purple blots on some leaves.
