Bit dissappointed about the back 2 plants turning out to be haze rather than Zkittlez, should have known with the stretch really but as far as growing they all seem to be doing ok. Im seeing more brown spotting appear on leaves near the top of each plant but after earlier diagnosing it as light stress, there's no sign of "taco-ing" anywhere so it could possibly be a PH issue again as suggested by another helpful grower. All my feeds have been between 6.2 and 6.5 though so not sure, just gonna try a couple of feeds with no nutes and see how they get on. It's close to flush time anyway so if they improve, i'll keep feeding just water for the remainder so all the nutes that have been unavailable due to PH are used up. If nothing changes, they can have one last feed next weekend and start the flush then. I don't think getting it wrong at this point is going to be too detrimental to harvest but time will tell.
