Why leaves curly?
NobodysBudsanswered grow question 4 years ago
heat or too much nutrients can cause 'canoeing'
looks less like nutes to me without coinciding symptoms, unless more easily seen than in picture etc.. Also, i see it's >80F? 85+ is typically entering grey zone of potential danger.
try raising humidity and the plant can handle a higher temperature without doing that... there's a limit to how much that'll help too.. consult a VPD chart -- google images or check my comments section of the gd.com profile here... it is hosted here, so no 3rd-party web site invovled. i credit where i got it from... want to say perfect grower? it's in the comments.

NobodysBuds is right, I had this same problem not long ago. It's heat or too much Nutes, in my case it was too much nutes combined with low humidity.

Hello friend, You stated that your lamp to plant distance is 4 inches only. That’s way too close in my opinion clearly you have light and heat damage. Also 82°F is a little too high.
Drop your temp down to 78°F and raise your light at least a foot. Plant should come back in a couple of days keep a close eye on it and good luck!

I would say light/heat stress....belw your affected area the leaves arent cupping....only at the higher part of the canopy. The light will bleach the plant and if it isnt corrected they will burn. Try moving up your light say 6” and see if that has an effect.
Good luck.

that is a sign that they could be to close to your lights so if you move the light a few inches away she should be fine

The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

CuppingOn the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.
