all of them together :) not individually or the math won't work out

That's way for you for work out. You need the manufacturers guidlines for hanging in flower, and that will be your maximum plant height. You can use some LST which I think you are there to keep her growing low and flat. She will at least double bite slow for nearly tripple in height. I would do another couple of weeks of training and then flip.

when the L x W dimensions are 2/3 to 3/4 of ending size you want.. should be safe. So a 3x3 should be roughly 2x2 or a bit bigger, but not much. (.66x.66= 43% or room for ~2.5x growth room and .75x.75 closer to 2x growth room) Some strains stretch more than others after switching to bloom. What i suggested covers 2-3x growth.

You’re plant needs fresh air coming in and out of that tent ph foliar spray and turn on the fans with some outside air coming maintain cool conditions with good ventilation and let you’re soil dry completely all the way before you water again

Could be heat or low humidity. Also, I don't see any other symptoms. If you've been a feeding steadily, can always give 1 extra irrigation of water-only between feeds and won't slow you down too much if not related.
