So the brown sludge came back strong this week. After 25 hours of being in the new water all buckets had big sludge buildup on the roots. For about 4 days I had to take the sludge of by hand and also take a lot of roots off that were too far gone or had dead roots tangled up in a knots.
I decided to treat this issue I keep having with bleach! Besides trying variations of feeds and doing plenty of rest buckets outside the tent with different feeds and ratios, they all ended up with bad smelling water and sludge on the air stones.
So now I have a ton of air pumps, 2 airstones in each bucket and decided to get smaller 2x2 airstones to get them really moving. The big 4x4 airstones got the buildup on the bottoms and it seemed only enough air was going to them to only produce air coming out the top or side facing up with no air coming out the bottom side of the stone facing down. The smaller airstones produce air bubble all around, so I’m hoping more oxygen may safe.
After treating with bleach at 1ml per bucket (2.5gallons) the brown sludge starting to slowly go away and new bright white roots were growing.
I built a custom scrog screen I plan to use if I can tackle this problem and not have to treat the roots so much. Fingers crossed I figure this out soon!
More LST and the plants are responding well. Minimal defoliation.
