RO and I use Dyna Gro Foliage Pro from clone through to harvest, I mix my Cal-Mag into my Dyna Gro to begin with so it;s already in there.
I use coco as the medium, the AUD and C3K's were being fed 4 x a day in flower, hand fed in veg. A few weeks into flower I add a bud booster.
I go really easy on the ppms because I usually have multiple strains sometimes all being fed from the same gallon jug.
Hope this helps, thanks for the interest.
I also started adding .06ml of Mammoth per gallon of nutrients 2-3 times a week throughout the grow until flush and harvest.
