feeding

hey folks
i have no idea what information you need so if theres any more just let me know

i am wondering how many times a day i should feed my plants for
its a wilma system plants are flowering 12/12 under 600hps
atm im watering them 3 times a day for 15 mins should i be watering them more then this ?

thanks for all the help

What do your girls tell ya? That's the biggest thing you need to go by..i've done a few DWC and flood n drain grows, but not familiar with how the wilma system is set up.
If your girls look good, then they're happy the way it is. Imo 3 times a day is plenty. Trust me, your girls will be the 1st to let you know if they're not happy.
