Could be nutes discoloring roots. Are they slimy? What is the resivour temp?
Res temp looks good. You can add h2o2 every few days if you want. If you flush you can run it double what you would regularly to kill bad stuff. If you are running any beneficial fungi or bacteria it will kill them. Otherwise I would recommend using it regularly.
ok thanks bro.
Someone told me that h202 might destroy the nutrients if mixed together so I am tripping out lol
Nah, never had an issue with any nutes. I ran house and garden, advanced, general hydroponics and dyna-gro. As long as you aren't adding any beneficials you will be fine. Do you have 30% food grade h2o2?
Where are all the big fan leaves? These look very weird.
all the people who lol dont know much about growing.
Removing fan leaves is an accepted practice, and the guy who said something about 35% killing the plant... that's not true
the problem here is of course the roots not the fan leaves, if anything, your plants want as little leaves as possible with root system taking so much damage.
hydrogen peroxide. enzymes full strength. pray.
also: add airpumps to the reservoirs. lower res temps (70 max). if there are plants with healthy roots, separate totally (like, disinfecting tools) from sick plants.
Removing fan leaves is only 'accepted practice' within the mythical cannabis forum forest. Fan leaves along with healthy roots are the driving force of a plant. More fans you trim less your plant will yield........
i thought so too, till I saw a side by side experiment...
