Nice report! I've got one on day 74 right now, and she's probably got another week to go. I grow under LED's and I'm starting to think this makes things take a few days to a couple weeks longer on some strains - at least from what I see reported.
I have the same problem with the leaves dying and getting crispy, and I think it's phosphorous lockout. My pH is fine, I use bubbled water, I've flushed her, but she's just ugly. Right now i have three other plants in the tent, all using the same nutes in the same flood tray and under the same lights, and they are all beautifully lush and green. Perhaps there is a genome of the Bubbleicious that just does this? It's how she ages - ugly and hard, like Sarah Jessica Parker. The Keith Richards of the autoflower kingdom.
I'll say, though, the buds look damn, damn good! Mines about 120cm, grown in a 2 gallon smart pot, and busy as hell. I'll post some pics I took this morning later. Nice grow, bro! Can't wait to try mine after that report you gave
Back plant is Bubb, front is an Auto Anesthesia that is probably 2-3 weeks out still. I'll get a better pic of the Bubbleicious - I really want to show how similar my nute problem, or just perhaps how it dies off, was just like yours. But still with fabulous looking buds. Have to do that later, though.
