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!

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Weird Curls and Holes
Okaaayyy so wtf 😂 I've altered light intensity and height multiple times at this point. I've ruled out pests. I think it's either windburn, heat, light, or a combination of all 3. It's a little concerning seeing as how I think mid flower is right around the corner 😓

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

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.

Any idea what is causing this crisping on a few of my leaves? I am maybe seeing some slight curling/taco-ing on the upper leaves too? I think the PH might be a bit high in my water too, it's 7. I've ordered a filter and some PH Dwon, the PPM was only 250. Related?

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

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.
