GMSgrowsanswered grow question 3 years ago Your at the high level for ph in water grows. 5.8 is where you should be set for veg mode. 6 to 6.5 for flower mode. Your ppm should be at 7 to 800 right now. Don't switch these to flower until you get thing back in health. Keep your water cool with frozen water bottles in and around your rez if you have one or around your planter. Watch new growth for results. Older damaged leaves won't heal. Cheers
