I don't have a clue about plant nutrition. lol. Unlike you, I don't pretend to know more than I actually do.
I'm a clown? That's okay, you're a complete fucking retard!
Tell me, what is that supposed to mean? You weren't referring to a CALMAG supplement? Perhaps you're adding bottled MILK to your soil to supplement additional calcium? What bottles were you talking about that supply additional calcium and magnesium, if not an actual CALMAG supplement? The OP asked about bloom boosters and here you are talking about a shit ton of minerals that should already be present in the soil WELL before reaching the flowering phase.
I'll ask you again, put your finger underneath each word I type and read what I'm conveying aloud to yourself: What 'bottled nutrients' do you suggest adding to your growing medium to achieve this perfect harmony of micro/macro nutrients that optimizes bloom conditions? Try staying on topic, and don't bloviate about some random thing regarding "certification" (whatever that means).
