For the left one, you might wanna check a guide for sick plants, 'cause it looks more like a zinc or iron def, i had some of those but I can't remember which is what... shame on me.
I used to rely on the comprehensive guide for sick plants here on icmag but to my shame, I can't remember where it is and I lost myself trying to find it..
I say that because I've noticed the plant on the left started to yellow in the middle from the leaf tip towards stem, unlike the plant on the right which shows the "healthy" bottom - up yellowing from the flowering N def. I don't think it's the ph.
Dunno, just an observation judging from the photos, hope it helps.
And I just been there... now I'll find it, thanks.... BTW the guide is in the top sticky section of the Cannabis Infirmary Thread.
Starke which par meter are you using ??. I think I asked before but forgot which one thanks in advance ,
It is a meter from Spectrum Technologies:

Been using it over a year now and have no complaints. I know there are better ones out there but this was affordable at the time. Around $340.00 if I remember right. Sure takes the guesswork out of adjusting height and coverage.
Lookin good in there Stark! Love the turn table and fixture set up. Are you thinking about vegging future cycles a tad longer?
Those trichs look yummy
