Well last night we dumped the res, flushed all plants and started out a bit lower on the PPM's. right now i'm at ph 6.0, TDS 800, and water temp 70*. given they aren't growing hard i lowered the co2 to 1300ppm during daylight hours.

as of today the plants still don't look any better. how long should i wait before trying another solution? two days of foliar epsom salts on 1/2 of them didn't make a noticable difference. i'm also back to the once-a-day watering method.

last q- if running in a sealed enviro, can you run too much co2?
