Hey /out/
I decided to clean my hydro res today and when I pulled the lid with plants off I noticed some of the roots looked a bit brown compared to the others (the basil on far left and the sage second from the right).
Does everything look good here? My water temps in the res are about 70F, the water is well aerated, and per advice from a friend I have been adding 3ml of 35% h202 per week.
