Some yellowing going on there in the middle. Overall looking like they are looking a wee bit peaked, maybe a little hungry? Couldn't say for sure without some detail. No perlite, how's your drainage?
Drainage is great used gravel mulch mix in bottom manure potting soil mix on top 2/3 of container the the yellow one in middle was me I broke it and am trying to save it had some nute burn in starting pots but clearing up sense moved to big pots been using 10-10-10 nute for last 2 waterings
Finally putting the experiment plants to dry not bad in this tent where I did that heavy pruning wound up with 1.87 pounds wet weight once dry should be around 1.3 or so. In a 4x4 tent with 600 hid light I would have to call it success my other tent just flipped to 12/12 and now I have to reseed this tent round and round we grow were we stop no one knows to all a good day
No way am i an expert but from what i can tell the leaves are canooing which means the temps are too high
I think they do that to trap transiring water
Please dont take my word for it but wait for a pro to confirm
