ironf1stanswered grow question 2 years ago I think you should've give them no nutrients at all at this time of their lifecycle.
and on my research I have found out, that you should start with even less than half the dose for autoflowers, maybe 1/4th of the dosage that's recommended.
But it will fix itself with watering...
I'm not experienced enough to help you with the flushing like granny adviced.. I would be scared to drown them immediately after that too 😂
