@PatriciaGant, I run ph 5,5 for rooting and 5,8 for flowering (5,6 to 6,0)...?!
ORP is oxidisation potential for fluids. Search google for hypochloric acid (DanChlorix) and try killing algea without killing the plants ;) My personal max is now 2ml/l for root fungae. Algae was an initial issue I had on perlite.
