1000-watt HPS 'barely' above the plants ? .. I'd be looking for light-bleaching, etc ... my little fan-cooled 400 HPS frys the hell outta mine, even with a 70-degree canopy ... :wtf: ... also, you didn't mention if your tapwater is city-chlorinated, or not ... if it IS chlorinated, and not thoroughly evaporated out (a strong bubbler speeds the evaporation up quite a bit), your FF 'Big Bloom' live microorganisms will die ... just a thought ... good luck :thumbsup:
