Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Leaf tips on all my grows turn upwards slightly. I'm using a 260w HLG Quantum board LED light which is about 2.5ft away from the plant and temps never get higher than 27 degrees with about 60% humidity. Could it be calmag deficiency?

Hello is it nut burn or to little nuts? The biggest plants are the ones affected. The big plants also have less dense buds and more white hairs but looks like they have the potential of more dense buds. The EC rises a from 0.8 too 0.9. They drink a lot of water. Have auto topoff

Curling new growth
All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss

Tips of leaves turning
The tips of leaves are turning up a bit. I guess they are doing that because of high temperature, but could there be any other reason they are doing this?

Leave issue
What is this? Nutrient burn, deficiency, fungus? I tried to look up the answer but it might be different things on different plants. Please help me diagnosis this. The white powder is DE and the small holes are from flea Beatles. But I’m more concerned about the browning.

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)
TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?
