are your reservoir temps in the 80's also??
My grow room stays under 85 degrees, but barely, i've never actually taken a res temp, i'm guessing about 80
res needs to be around 70 or less to prevent root rot
no shit? I did not know the res could be too warm. I was always told you want it warm so the nutes flourish in the water.
Another thing, I noticed the root roting was only taking place in the air pocket of my res. Is that still from the heat?
Money is right Krimet.....80 is too warm. 70 is considered ideal in hydro....going up from there increases your chance of rot.
I personally think your roots look pretty good right there....there is SOME browning but that actually may be staining from your nutes.
Are you using a zyme product such as Cannazym, Hydrozyme or something similar? You really NEED something especially if your res temps are that high. It will help alot with keeping your roots healthy.
Also consider a good flush to help get rid excess salts, ferts etc that build up in your medium and cause their own issues with root rot, fungus, disease etc....
Krimet your plants look quite good. Good work and healthy, happy looking plants. :thumbsup:
I have only been using h2o2 like you said, 2ml per gal every other day.Should I also top my lst'ed plant so that it can focus on its secondary growth?
If you are into flower then no....don't top because you won't get more growth at this point...it will just stay gone. All your good topping chances are over. In looking at the photo above of your plants I see perhaps 3 leaves sticking out over buds that I would remove....the rest I would leave as is. They look great and will use those extra leaves later on for energy and nutrition.
I forgot I told you to use H202....are you using the hydro kind (35%) or the regular grocery store bought stuff (3%)? That will work for you for root health as far as killiing stuff off but is missing a few of the things in the zyme products. But i'd stay with your H202 for now since it seems to be doing a good job for you..
PS....Rinse the dark portion of your roots off with some plain H202/ph'd water and see if the brown stuff rinses off. I have a feeling it will. ;)
Would you remove any secondary leaves that are bigger and covering other bud sites.
