Hey everyone! I'm concerned about these roots, I've been concerned for some time as this is a recurring issue and I'm trying to get to the bottom of it.
1. The pictured 6" rockwool cubes were recently moved from the veg room (ebb and flow) to the flower room (top drip). two different plants, different strains, from different trays, off different res's (there are four trays and two res's in this flower setup.)
2. the concern is this - in ebb and flow veg room the roots come out of the 6" cube white and furry and gorgeous. in just 5-7 days in the flower room with top drip, some roots begin the discoloration as seen in the pictures.
3. the roots lose their pearly white, and the discolored roots pictured here for example are easy to pull off - they are dead/dying.
4. the ebb and flow in veg is fed by a 40 gallon with GH nutes, 500-700ppm, 5.8ph.
5. the flower room top drip also has a res underneath, 10gal, GH nutes, 700-900ppm, 5.8
6. the past harvests have been decent but not stellar. every stellar heavy harvest has one thing in common - happy white roots! I'm using drip clean (house and garden) at recommended ml's 2x/ week. changing the res 1x / week.
7. between harvests i'm scrubbing trays and res's with little diluted h202 30% or 100% bleach. this time i used h202 and vinegar first. then i gave a heavy dose of bleach and rinsed the entire system thoroughly so no bleach or bubbles remained (i drank out of the res to make sure i didn't taste bleach).
8. i've been told drip clean will kill any bad pathogens and pythium. i don't believe it. i believe something is in or getting into this system to cause the roots to become rotten, discolored, etc. i'm tempted to go back to ebb and flow in the flower room! but all pro's point to top drip as preferred.
any insight, suggestions from pro's out there who have had experience with this type of situation is highly appreciated!
