i'm in the 6th week of flowering 2 plants and i accidently used veg nutes in my reservoir instead of flowering nutes. i did this last sunday. friday i noticed they stopped taking in any water and the leaves were turning black at the tips and shrivelling, i rinsed the reservoir and roots and i put them in nothing but clean r/o water and have had the lights off for 48 hours now with no improvement. HELP !!! any ideas?
