Are these being top fed currently?

What PH are you feeding at?
...and what is the background EC of your water?
It's Not What You Know, It's What You Can Prove
Ph range must be 5.5/6.5ish . My plants are around the same age , my e.c is .4 and thats the max i would go ,not .8 thats too strong .
Until the roots hit the water ,you gotta.top feed .

When water temps goes up ,it releases more nutes making them avail raising ec for what seems no apparent reason ,and also raises ph ,making the water sweeter( alkaline) so its.important not to let those water temps go ballistic , mine goes.from 18.3 nights and sometimes 19 by lights off and ph and ec are stable exept if plant is uptaking alot of nutes and water .
