did you do this with just clean water? I'm guessing you don't have EC/ppm meter? testing EC of this runoff would of told us so much. You see, if EC out the bottom would of been some high number combined with the pH coming out lower than what you put in, right away I would know this is all from too much nutrients built up int he soil, and I would recommend clean water only at pH 6.8ish and the plants would jump back to health. but if this is all caused by low nutrients, the total opposite, and they just need more food, EC out the bottom would of been real low, because the lower pH could just be because you've been feeding 6.3 for a while and not actually indicating nutrient buildup and that's just where it settled.(nutrients are acidic, peat is acidic) I'm actually stuck on what to suggest you. thinking out loud because this is not a guessing game.. there's more to it than I wrote just keeping this short. food or no food.. hmmmm
This is what I would do:
I would mix up some lucas formula at 5mlMicro - 10mlBloom @pH 6.8 and (only when they for sure need to be watered) water them like mad man until the pH coming out the bottom is almost a match, but doesn't have to be perfect, just bring the pH up a bit in the medium where nutrients are better uptaked and a reset/replenishment of balanced nutrients down there, no matter what the concentration we end up, just that it is balanced, and complete food source left when we're done, and the plants should jump(once they start drying from this big watering). then leave em, and the watering after just clean water pH 6.8 again, then and at that point see wusup with the plants. explanation: If food is low in the medium(which we do not know), and we just flush with clean water which most would suggest, you would have lost time and more yellowing. if food is high in the medium, causing pH to drop since nutrients are acidic and we go feeding them food, you could make pH drop lower and burn the plants and fuck up crop this close to end even more. so a slight leaching of the soil, with a complete balanced nutrient solution, low EC, at proper 6.8 pH until the runoff is close to what you put in, and we would have partly reset the medium and flush any imbalanced elements at same time.
sry so much blah blah, I'm trying to explain my thought process, not just tell you what to do and leave.
I am sure some will disagree with me here, but I don't see them putting themselves out there trying to help, probably would only respond to me after the fact working off my words, which is bullshit.
small flush with 5ml/10ml lucas at pH6.8 should get the job done and plants will jump for final push. then clean water watering after pH 6.8 again.
(The one mistake that I can see coming from this, is if you do not do it with enough runoff to get the end result as I stated.
)
