@accela_resonance, usually you won’t see burning so uniform in nature. The leaves looked to have perfect markings where the burning was lol. That was my only thought. You seem to have got it under control tho. Good stuff man!
No I didn't test the runoff, i should do that next time i have to flush. I'll try to identify if it is a deficiency and keep a close eye on it. It hasn't affected the young leaves as much and the burn seems to have slowed down.
I think i did water with some higher PH water once or twice
Lolli popped + defoliated aggressively a week before switching to flower.
I'll probably defoliate a bit more this week. Clearing out the lower material, small branches that have regrown, small branches that won't have enough space in the canopy and some larger leaves blocking nodes.
I practice tucking between defoliation
