5ml Cal/Mag per gallon and 15ml veg nutes for every 5 gallons or so.........At this stage, I want the ppm around 275-300. If they lighten up too much (not green enough), thats when I'll start adding more nutes to the mix. This strain is hardy and will grow on the taller side if you let it. I'll probably top them at 3-3.5 weeks, let them veg for 5 weekstotal and then do a very heavy defoliation when I switch to flowering.
Remember too, they don't put off a lot of leaves per the breeder, but I've heard that before and still got a ton of leaves under these LED's.
