Sounds like it’s doing what an auto is supposed to do. Don’t want early flowering, don’t grow autos. The clawing of the leaves shows it’s been given too much ferts, specially since it’s in FFOF soil which already has a lot of ferts in it.

@Hellraiser is right on the money with the FF OF. It’s fairly hot soil. Usually OF will not be depleted of nutrients for at least 4-6 weeks.
