the ph of RO water should not be that low. are you testing it before you add any nutes or anything in it? after the RO process is complete the ph is either at a perfect ph of 7 or it's much lower but much more susceptible to ph swings. next time you are mixing nuts try putting your nutes in before the ph up/down and see what the ph is
