Growth has matched or exceeded the other fem seeds planted at same time. It may have looked a little funky before transplant but really seems like it is worse after - though three other plants would also be in *potentially* tainted coco but show no similar symptoms.
it's getting less than 1.5 EC feed and tbh if it does require some esoteric feed, it's just goin in the garbage, lol.
I think substrate or genetics seems most likely.. thanks for the help. Giver her another week or 2 and see what happens. I'll double up on runoff from this pot for a bit in case it is substrate related. I've got 4-6 more plants than necessary, so no biggie either way.
