IM GONA PUT SOME PICS ON AT AROUND 11 TONIGHT, PLZ AWAITE THEM AS I THINK IV GOT FURTHER PROBLEMS, QUITE ALOT OF LEaf is dryin out from bottom upwards, starting brown then going yellow

my system is a ikon 18 table, pumps water in at top then runs down back into tank then back round again and again, ph is kept 5.5 - 6-2, some times it wonders out so it gets corrected every time it does, feeding hydro ionic bloom, on my tester my tank reads 0.7 - 0.9

pics will be on later
