Rez is too small. WHats the temp of your rez solution ? Your pH will rise with that 3 gallon rez, quickly. Root rot it sounds like, thats when the water smells like shit.

I'd do a rez change, scrub that rez clean, squeaky clean. Then I'd run straight ph'd (5.6 or so) water and Flora Shield for about 3 days. Watch your pH closely. Then do about 1/4 strength SuperThrive, and 1/2 strength Flora Kleen.

NO NUTES for now. With pH drifting that high you are having nute lockout anyways.


Oh, and COVER the top of the netpots. Light shining on the tops of the pots does nothing but cause you grief.

Keep us posted, and best of luck.
