Looking great, man! Nice job!
I agree that that particular plant wants more PK than the others. I would give her a bit more of whatever PK booster you are using. Keep it up, bro!
Thanks for stopping by! I have gone to full strength Connoisseur bloom a+b and cut out the Cal mag Xtra bc of all of the added nitrogen. (Connoisseur bloom has a good portion of micro and Cal mag in it) they are responding much better than before so I will continue to do this until flush I guess.
