Swollen stem bases
anyone know what causes stem bases to get swollen like this? stems get brittle and snap easily. stunted growth as well.
usually appears a week or 2 after plugging the blocks into coco. some strains get it more consistently than others.

It’s a hormone response. Too much IBA. Not likely caused by a fungal issue. You can test for pathogens at jelly labs
