Taco leaves

[Blackanwhite1]

Quick question guys/Girls.........

I have a few leaves on my girls like this

Is this due to high temps?

Thanks in advance.

It could be. What kinda temps? Also, there's a form at the top of the infirmary, we'll need all the info to help out.

Thanks for replying. At their highest the temps have reached 90F

Hard to say from that photo. Looks more like the leaves are folding in from both sides, rather than folding along the centre line of the leaf?

What light is it under and what height is the light?

I say high temps, light burns have more of a yellowing effect around the leaves IMO. What’s ur humidity

I have 6 plants under 2 600w HPS. Their approximately 18 inches away from canopy.

Humidity is anywhere from 40% up to 60%

Not talking about light burn, I'm talking about light stress.

Light stress will show as the fingers on either side of the leaf raising. If there is way too much light it can be very extreme and at first appear to be tacoing.

Autos or photoperiods? And what about the earlier question..... are they folding in from both sides, or folding along the middle of the leaves. The answer is there mate.
