Switching to flower how should i feed

Ww switching to flower 12/12 . T5 4 bulb 3400k.
3 gal. With fox farm.
Fox farm fert.
Going to big bloom
8 weeks in veg.
RH 30 @ 75 degrees f
Normally I feed twice a week . Let the soil dry out then feed.
My questions are do i still use the fert. With big bloom and should I switch to daily feeding ?
I also have 2 clones from her problem is I have 1 room but 2 separate lights I can separate with a curtain. Can I veg 12/12 with the flower stage ?
Big thanks to all of you through this first grow!!

Hello there...I can try to help you. I normally will feed veg nutes for first 10 days to two weeks after flip. Once true flower begins, I start to slowly cut back nitrogen, while increasing p and k.
I allow the plants to tell me after that when they may need a spicing up of a little extra n, but not a lot. Too much interferes with Bud production, they turn leafy and not very good.
As far as the veg in same tent as flower...not a really good idea unless it is completely separate environmentally from each other.
Hope this helps.
