Yeah, but what would be *more* ideal, tap with 180ppm, or RO water and adding cal-mag to make it 180ppm?
Illusion Reviewed by Illusion on . First grow Recirculating DWC this grow journal starts off at 37 days into veg. finally got the three babies into the system after a 4 day struggle with leaks they've been flushed with r/o water for 3 days. before they were flushed, i had the ppm of the reservoir up to about 450, cal-mag and GH's MaxiGrow. I noticed slight burning of the tips. Unsure if it's from high ppm, or heat stress. Decided I will reintroduce nutrients *slowly* I should only use cal-mag when i notice signs of deficiency, right?
