If you have plants in DWC that have roots they need feeding starting about where you're at at a week.

If they have roots they need nutes. Calmag. is an additive, or supplement, to main nutes, with ro. You will need 2-4ml per gallon.

Hey Medichroic,

I've got a plant growing in DWC with AN but using the bloom and grow 2 part. When the roots start peeking through the rockwool I just add calmag for a week or two. When the seedlings get a few leaves I start them on the AN 2 part following their online calculator.
