Cotyledons curling upwards - the others didn't do this? :(
I'm not sure what's going on! The two others didn't do this. I'm using ViparSpectra XS2000 at 24" distance and 50% intensity.

What’s Happening Here With My Leaves?
Not sure what’s going on here. It’s happening to 3 of my plants and I’m not sure whether its good or bad. I haven’t watered in 3 days so I don’t think it’s overwatering because it just happened today.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Deficiency?
Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk

Crumbly fresh leaves (week 2 flowering)
About those crumbling leaves: does anyone know what the reason(s) might be? As I've said: semi broke some branches, there's 2 fertilizer tablets in there, and I sprayed them with boomboom spray 3 times in total over the last 4 weeks.

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

Praying leaves
The leaves are stretching up (praying leaves as I understand). It's just 1 day after topping and I would expect some stress, is this a good or bad sign? I fear I might have topped them a bit too early.

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

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok
