Looks like it could be afew things. Heat stress could be causing the curling. The brow spots look like a calcium deficiency to me. Happened to me when my ph was off. I second making sure your calibrated. And also make sure your ph is on point when feeding. Also is your hand feeling uncomfortable under the light? It could be to close to the plant but hard to tell in the pictures. Your issue I most likely calcium deficiency /Ph issue.

Hello Any chance you've recalibrated your ph pen lately just to make sure its running accurately? Otherwise those high powered lights will cause curling(especially the curl upwards) and discoloration if they're putting a lot of heat out and getting a tad close to the plants.

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

Day 20 Flower. Leaves curling Leaves 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?

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?

Cupping On 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?
