That is generally a symptom of heat stress, try lowering the temps if you can.

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?

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?

Help: potential over fertilisation or over waterning
I used Biobizz bio grow, 2ml/L and sprayed them more than usual. 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. Check the diar

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

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !

Hi guys, I’ve noticed the leaves of 2 plants are curl upwards. I think overwatered, Day 9 I’ve watered two times (wrong) and after checking Day 8 too. At day 10 I've didnt watered, and today I've seen the soil dry, so I putted 100ml water. What do you think is causing this curl?

If I’m correct but who knows that most likely over watering or my lights are to close?

Any ideas on my lower leaves cupping? I'm thinking a root issue from overwatering. I last watered 6/11 and this started showing on 6/13 and has progressed. Soil is still moist and fungus gnats popped out of nowhere this week as well. Have SNS 203 for next watering

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?

Guys been going great until I checked today. My top leaves turning grey white and crunchy on 2 plants. 3rd plant ok. What do you think too much Kool Bloom? To much heat from the light?? I don’t think it’s the latter I decided to flush for 2 days to clean it out??
