Kind of looks like it could be both light stress and calcium issue.

Runtz muffin curling leaf update
I posted a question yesterday regarding leaves curling up on my 10 day runtz muffin, presumed heat damage but after a feed and 24 hrs she's come back from it, recently upped the light to 400w, do you think they just take a bit of time to adjust to it? They all seem good now

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !

Question on leaf curling
My plant was flushed last week and has now used all the water from that. She showed some curling tips this morning. Any ideas what's going on? Light set for 40 DLI. If she needs something, I want to add it today while she's thirsty. Thank you for your help!

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?
