Experts, please help. I have been struggling to get rid of root rot for the past several weeks. I'm not quite sure how to proceed at this point. My plants are struggling along - not recovering, but not dying. I'm about to give up on DWC and go back to soil.
Details:
30 days vegging
DWC tub, 10 gal, 2 plants
Two 60-gallon air pumps connected to three air stones
Res temps are ~68F
MH light about 14" above plants
Air temps range from 66-84
DWC container is solid black
Lid has reflective tape - no light should be getting in
Roots look like they have brown snot on them. One set of roots had what appeared to be green balls (like algae) underneath the slime.
Roots in the water are pretty health. Those that are in the air gap between the water and bottom of the next pot are the worse.
I have tried:
1. Blocking all light
2. Adding airstones.
3. Adding 3% H2O2
4. Adding Hydrozome (at different times from the H2O2)
5. Dipping the roots in a very strong H2O2 solution, only to have the rot come back the next day.
6. Changing the res weekly
7. Adding 3% H2O2 to the res between changes
8. Using Foxfarm organic nutes (~650ppm)
The leaves are wilty - they look like a plant that's overwatered (which I assume is not enough air due to the root rot). I have had some PH problems; if I PH at 5.8, the PH climbs within 24 hours to 6.8. I figure I need to take care of root rot before worrying too much about the PH.
Last night I changed the res. I let the roots soak in a pretty strong 3% H2O2 solution - it's was bubbling, but it knocked down most (not all) of the slime. 24 hours later all of the slime is back on the roots.
Any suggestions? Do you need more info?
Many thanks in advance.
