She’s fine, let her dry out a bit! Also add some Magnesium sulphate to straighten her out! Cal mag her up! Mainly Magnesium though!

Theirs plenty of nitrogen though, see how the leaves are slightly turning? This is a sign of too much Nitrates/nitrogen!

Too Much Light?
Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Light burn or nutrient issues? Female?
Does this look like light burn and maybe a lack of nutrients? Also can someone confirm that she’s a female or is it too early? I am first timer and think I see her lady parts already.

Organic soil 0.1-0.1-0.1 60% soil 40% perlite soil is pretty damn dry on top
The girls seem to be doing ok, little bit of curl up on some of the leaves, which indicates I over watered, humidity is usually 40-50%. I water 1 time per day with a mister, it's only been last few days that leafs curl up. Is it time for nutrients?. They are 10-11 days old.TIA

This is a 27-day auto plant. The problem is that the leaves are crunchy and curled upwards. Soil pH measurement 6.5. There was a fan right in front of it, I changed its direction 1 week ago. Do you think this is a disease?

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Curled up leaves on day 7
I started a plant ten days ago and from the 7th day some leaves started curling upwards. I flushed the soil one day before planting the sprout and watered it again on day 9. I use the Fecida 600 lamp 16/8 day/night. Does someone know what could cause the curling of the leaves?

Overwatering?
Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency? One pic is upside down, I wasn't stoned taking the pic, honest 👀

Phosphorus def in veg?
Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?
