I am using rhizotonic that's a little old but the problem started on plain water while flushing. My theory after some research is the plants being in heavy veg growth are feeding on the nitrogen in the
nitic acid. Still not sure why adding the aqua vega is dropping the pH tho. Never had this before, even from the same bottle, which isn't very old. As I've added more feed the swing as slowed backing my theory the pH down is being feed on.
