  1. Hey guys need some advice! Ppm 700-840 don't think it's nute burn light isn't that close at about 40cm 600w cool tubed. P.h rises to 6.1-3 before i can get it back down to 5.6-8. Could it also be from adding a silica additive and not coping to well? Or maybe from constant 24hr water cycle recirculating in clay balls? Using house and garden hydro a and b Thanks

  2. Flush the rez, circulate 2-3 hours then re feed at 50% less

    flush again in 2-3 days, then continue as normal

    maybe not so much nute

    good luck
