Looks like the white fuzzy mold you'd get on rotting peaches. Appears overnight 100% mortality. Additional symptoms are a damping off looking effect, mushy stems. It's not always on the stems, those are just the pics I took, it can appear on the leaves first as well. Lost 4 trays of clones 1 month ago to the same thing at this location, a house grow. It's happening again.
Have tried treating unaffected clones in the same tray with foliars of h202, silicon, organocide and ph10 water. No effect, it spreads, they all die.
Since then have treated the location with a concrobium mold fogger. Threw out all trays and humidity domes. Threw out all rockwool purchased with that last batch. Treated all surfaces, floors, walls, etc and equipment with physan20 at sanitation levels.
For this batch treated the ro water used for soaking the rockwool with h2o2, asprin and silicon. Foliar sprayed clones with ph10 water with silicon (pro-tekt). Let the leaves air dry completely before putting under humidity dome.
Started to see mold, lost an entire tray overnight. Every clone covered by mold, like a big cotton ball filling the humidity dome. Tossed that tray, disinfected the clone cabinet again. Took off the remaining humidity domes, removed affected clones from remaining 7 trays. Hit the room and clones with a sulphur burn (nothing to lose at this point), left the trays uncovered overnight.
Death by cotton ball slowed a bit, still lost many clones, hit them again with sulpher burn, left them uncovered overnight.
Lost some more. Time to experiment since they're all gonna die anyway. Covered one tray with dome since the rockwool was drying out, treated one tray with a physan20 (@ 1ml/10gal) and silicon foliar @ ph9.2 [these will not be consumed or put into production].
Dome tray ravaged by mold overnight, 50% dieoff. Untreated trays 10% mortality, physan20 tray 5-7%? mortality. Spray everything with physan20 and silicon foliar. Spray dome tray as well, let dry, spray inside of dome surface with same physan20/silicon mix, replace dome.
Overnight, throw out dome tray and dome; 75% dieoff only a few clones remain out of 98 starting. 10% dieoff on uncovered trays.
Out of over 700 clones in 8 trays, 6 different strains, less than 30% remaining.
Halp? WTF is happening?
