Day 39 of flower

just keep it healthy, you can test 'boosting' this or that, but if in the following 2-3 weeks you see issues, don't make up excuses as to why it wasn't from 'boosting' things. If it's not showing deficiencies, she's fine. You can systematically try to 'boost' various elements, but do so 1 at a time and see what happens... then if it doesn't resutl in toxicities, adjust formula going forward, mix and repeat. The whole - blast it with p and k in flower is a poor perception of reality. If you are already providing as much as it can use relative to local variables, more won't help anything. Why someone wouldn't already be providing as much as possible is the part i don't get, lol. if anythingn causes a visible build up in leaves, the plant is taking in more than it can use... it's not foie gras.

Keep the feed steady if she's doing good on the schedule you have atm then keep her at that it's not a case of upping the feed and boosters constantly it's finding what she likes and wants..

Best to take pics useing white light for diagnosing and such. Hard to see things in blurple light.
