New to Hydro growing.....What are the light Times for Veg vs Flowering

What are the light times for Vegatation vs Flowering ?
What are the best nutrients for food for the Water ?
Do you stop feeding for the last couple of weeks of flowering ?

I keep my lights on in hte dark outside from 6pm-6am my lights are on, but htats in summer for the heat from my ballasts.
during winter I switch it around as we need the heat during the day than at night to i keep them on from 6am-6pm
best nutes? seems this will be the third time for that question. I use GH, Tiger Bloom and Grow Big and Kushie Kush
I flush my ladies from the last 2 weeks to the end and i am in hydro'

Thanks for the tips.......When you say flush are you referring to water only and no nutrients ?? What is GH ?

GH = General Hydroponics, I use them to and they are great to work with- they have a dosing chart on the back of each bottle for each stage of growth you are in. Flushing is giving only water, and yes you will want to do this 2 weeks prior to harvest to help enhance taste.

18 on and 6 off for veg
12 on and 12 off for flower
