Please don't go by the feed charts of ANY nute line when feeding an autoflower - you will massively overfeed them! I think you're in a good spot right now with the amount you're giving them and I would wait to increase the amount, but CERTAINLY not double the dosage! That's just asking for problems down the line. With autoflowers, less is more... and I've never grown an auto (they're ALL I grow) that has tolerated the full strength of any nute line.
You've already started them on Bloom nutes and that's fine BUT you've also chosen to do some very high stress techniques on plants that don't like stress at all... You've got to wait to do ANYTHING more until you see them enter the pre-flower stage.. which, hopefully, will be soon - maybe even next week if they've had time to recover from the topping/mainlining/defoliation. You're treating this lady like a photoperiod and she's not... Back off, let her do her thing... you're trying to control a lady that doesn't WANT you to control her - she only wants you to give her what SHE needs so that she can perform as she's been programmed to perform...
Good luck... I hope she'll recover and give you a good harvest...
