PH does sound too low, probably because of too much nutrients. 8g is a huge pot for those little 3 foot tall plants. There's probably lots of unrooted medium in there that's so packed full of fertilizer salts no roots want to live there. Soilmixes store nutrients which means a plant basically doesn't need any in it's water at all until it finishes filling the pot with roots. If I were using 8g pots, I'd probably veg them up to about 6' tall before flowering, by which time they'd probably need full strength nutrients because they'd be potbound. Also, flushing with distilled or RO water won't help bring the PH up as effectively as using your tapwater, especially if your supply is a bit hard like mine. Hard water contains calcium and magnesium that help to buffer against low PH, as well as supply needed plant nutrients. A good flush with (hopefully a bit hard) tapwater followed by no food at all of any kind until you see growth will probably turn things around.
