Raise N & Cal Mag.
But first, rule out *potential* pH problems.

not at all. I don't see serrated curved up leaves.
bottom yellowing = N lacking
overall plantcolor lightish green = Mg N lacking
looking again at the pics I can't seem to make out symptoms of Cal lacking, but quality is poor.
Would emphasize more N, but not too much bc your already in flower.
How is the stretch expected, how would you prefer?
Feed CalMag EC 0,3-0,4, ratio 3:1 or 2:1

Initial foliar application could be done right now and will never overdo

What are you feeding? Brand and amounts. What pH are you working with?
Are you in coco? How far into flower are you? Are these photo plants?

Yep they are all in coco.Man I haven't even checked the ph I've just been giving them what it says in the cx hydroponics book 1m/L coco base A, B plus head master and superior potash. All from CX hydroponics.only in the 4th week.but the yellowing is getting worse I only feed them coco base A B last night.might have to pick up one of em blue lab ph pens.could moisture do this man? Just wondering because humidity rockets uptown 70% over night even with fan on fully.

You'll need to manage your pH growing in coco. Anything less and you're most likely going to have issues. This is where I'd start.

pH drops will work fine; unless you're color blind...good luck.

4 weeks in...you're at best halfway to the finish line. Be patient...they'll fatten up the last couple weeks. You probably have 4-6 weeks to go
