I always start my clones in DWC at 300ppm. For me that works out to slightly less than 1ml/L of all 3 of my 3-part AN nutes.
I did a test a while back and 1ml/L Grow gives 85ppm, Micro 140, Bloom 110. So for a 50L tote of RO water I'll put in 47ml of each. I don't bother with CalMag right off the bat. In a week or so I'll start adding small amounts of the nutes to raise the ppm as they start growing faster. I might change the nutes after the stretch but usually just drain some off and feed only Micro and Bloom Lucas Formula style. Big Bud too of course.
