SOS fellow growers! I just started out with an Aeroponics set up, and still i am pretty much a rookie with it. the first few days - no roots were touching water yet - my PH would go up from 6.0 to 7.1 overnight; it stabled out for a couple of days all around 5.9-6.1 but now it is the other way around - roots touching water - i would have PHed it to 5.9-6.0 in the morning and then the next morning my PH will just DROP down to 4.7, what can i do about this? i am not feeding yet, PPMS are around 130. i haven't used Hydrogen Peroxide yet, have read it may be because of root rot (?) when checked up on the roots they all look nice and super white... any tips or comments welcome! happy growing!
