You Heard This Before, But What Is This?

[trix]

Day 3 of flower, started happening right after I switched rooms.. it's really noticeable under the HPS lights, issue seems mostly on the top leafs on the plants farthest from the inline fan, 3 1000w hoods. I'm thinking light burn? Ph 6.7/6.8 temps 78-80 humidity 54%.

 

I'm gonna pick up another inline fan in the morning put in in between lights 2 and 3.. should push out an uhh lingering heat. It's not hot to the arm at the plant level, which is 3ft from the hood?

Well shoot I'm on my phone and have no idea how to post the pics..

bugs, nutes, ph, heat.

 

one of those, glad to help haha

 

I would eliminate heat, as it's uneven for a heat burn....

 

looks like nute burn

most likely bugs

roots or ph swings.. seems a bit high PH.. is this soil or hydro. for me 6.0 for soil ,an 5.6 - 8 hydro..

she might be looking for a bit more cal mag? add for just a few times.

just my two cents, but I have seen my lady's do that and cal mag fixed it.

But I grow with leds.

or could just be normal in flowering as the plant transition from nitrogen to phosphorus.

Have you grown this strain before?

Could it be mechanical damage from the move?  It almost looks like the tops were rubbed.  I've gotten leaves that look like that from a fan pushing them against a tomato trellis, not enough to crush it, but enough to kill part of the leaf.

And that top leaf looks like it could be some water or condensation on the leaves when lights are on.

I agree with t-pain, either nute burn or bugs. Probably nutes.

Phosporus or cal/mag i would say, but without more info wouldnt say for sure. How do the leaves on the bottom of the plant look? what medium are you using?

Take a good peak in your medium as well.

Without a comprehensive analysis of your grow we are just guessing.

Looks to me like ph fluctuation. Check this out... http://www.growweedeasy.com/ph-fluctuations-cannabis

That's debatable
