Hey AFN,
I re-use coco after each grow and wash it out and make sure the medium PH and the Water PH match after repeated rinses. Never had a problem but this 3 gallon eco-pot(re-used) has killed 2 quality seeds(RQ auto NL, and then HVYWGHT Dreammachine) both popped in 2 days, planted them and they both broke soil the next day(the first one died in the same fashion, i then planted the next seedling(DM) in the same pot). Neither took off the first died(auto NL), they just shoot the first pair of fan-leaves barely. They never take off and the cotyledeons yellow and die after day 6-ish. all numbers are in range ph, air temp, dry humid, I only add superthrive at 1 drop a gallon and rapid start at a 1/4 for Drain to waste.
Meanwhile i have a 1 gallon ecopot with the same re-used coco taking the F off. I ended up pulling the second faltering seedling up and carefully and re-planting it in a solo cup (coco 5.8).
Anyone seen this ?
