[vickg35]

I am in my 5th week of flower , growing OG Kush . I noticed a few leaves canoeing up , not quite sure why . tried researching but couldn't find a straight answer, someone also had told me its normal but I want to be sure. Any help is appreciated!

Maybe heat? What temps do you have?

I have temps at 86° , light is 400w hps about 16" away

You have 86° at the top of the plants or below. I think this is the problem. Put a fan to blow directly on the hps.

86° is too hot. Not sure if that's the cause but I'd definitely try to get that down about 10°.

Also, move the 400hps up to about 20"-24".

Check your PH as well. I've seen the margins curling when PH is too far out of range.

4 out of 12 plants from seed exhibited this canuing on the main terminal or top leaves. 3 out of 4 are male. I have increased air flow and lowered the temperature. She looks okay, but I am altering the climate for 1 female..
