Leaf tips curling up are an indication of LED burn. I’d suggest trying to raise your LED lights.

Leaves turning yellow from the bottom up
My older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx Its only on 4 leaves rn

Does it look healthy?
Does it look healthy because the main leaves on the side are sometimes down on 1 side and up on the other

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

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.

Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Leaf Symptom Diagnosis
The leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.

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?

Weird looking seedlings? (uploaded vid)
My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.
