flushed should I feed.

Hello all.
Having some troubles with me ladies. 37 days into 12/12 and the buds are everywhere. I really don't want to screw it up now when the end is in site. I think they are either P or K or zinc deficent. I have throughly flushed them 1 hour ago. Should I feed them now? I am going to use peters 20.20.20 with Micro nutrients at half strenght. What do you think growers?
please help
many thanks from Afro pulling his hair out.

HMMM, well you probably flushed all the nutes that were in the soil, so I say wait a day or so, then feed. Maybe someone else can step in here and give some input.

just wait like your normal watering.i mean: wait the soil to dry out and then feed maybe 1/2 strenght imo. Cheetah

Wait till dry up to your knuckle when you put your finger in the soil then give them nutes.
