Unhappy seedling
See the photo of one of my seedlings that appears quite unhappy. My guess is light/heat stress, BUT I have 8 other seedlings growing right next to it, under the same grow light, in the same soil, that are doing just fine. See 2nd photo of another of the same strain that's fine.

Why the canoe effect on Fan leaf
Can anybody help me ID what is happening to these Fan leaves, at the top of my Black Willie. Leaf temp is 1c cooler than the room. Leaf 22c, room 23c, rh%55, lite distance 45cm. The leaf is showing that its folding like a canoe. Always thought that was signs of “ “too hot”.

Leaves curling up
My plant seems really healthy but some of the leaves are starting to curl in, I was just curious if this is normal or should I be concerned of a deficiency? My light is 24 inches away and a steady 80 degrees. So I highly doubt heat is an issue. Maybe a slight nute deficiency?

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

Leaf tips curling on top
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.

Strain starting to canoe any ideas?
So I have 3 plants of the same strain SSKM. 2 of them are starting to canoe. 1 of them has no discoloration on the edges of the leaves, the other does. 1 without discoloration is in coco coir, other is in soil. Don't think it's over watering or underwatering

Classic N toxicity (:
Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)

Starting Training
I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?
