got some twist.. is that coco?
don't give nutes for a while, even in coco. Even give a health 20%+ runoff as soon as it won't drown the plant.
if it is coco, check brand quality and reviews online. Ill-prepared coco will make growing very slow and difficult. dark green leaves, twisted, gnarly looking etc.
Bet she busts out of it in less than a week, if not substrate-related. don't fertilize. the seed is packed with power for two weeks.
