all depends on what the trichs look like. looking like she has used just about all of her stored nutes, so she prob cant fatten up too much anymore. if ur trichs are clear, than go with 2 feedings of PK but u still prob wont get too much out of it.
1st set of pics, 3rd pic- plant on the right- her buds look a bit denser and she looks alot less deficient. if this is the case, next time keep feeding until u r ready to flush.
if ur trichs are cloundy, flush and harvest. if clear, and it was me, really clear-no milkies, I would feed her a dose or 2 of veg and bloom nutes 1/2 strength
either way they look good
