Water/feed when the pots are dry. It might be 2-3 days, it might be every day. Learn your girls.
I feed, feed, water, unless a particular strain needs less, but do what works for you. Measure the runoff ec vs feed to help guide you. If the runoff is close to what you're putting in, give it water the next time.
One of my girls in FF soil pot is like hydro right now, she can handle food almost everyday lol
