Tiny c99xblueberry fast

This has been the wierdest grow. She beef and seems healthy but I have no idea what going on with her. She too 2 weeks to germinate, then when she did her first leaves were at soil level. Then all of the sudden she exploded and hasn't stopped. No one top of that she has a deficiency I can't figure out. Oh my soil, gave her more nutrients be no change. Just going to keeping doing the usual and hope for the best. Buds look good and smell is nice.
