That's alot of residual for ro.
For hps your revised #'s look like a good starting point.
Jack's adds:
.25ppm mn/zn
.50ppm fe
.05 ppm cu/mo
.10 b per 120 ppm ca in their boosted CaNO product.
If your media has sufficient balance and sufficient mg you can lower mg even more once the plant roots in well.
Ca controls cytokinins and is largely responsible for internode length. Move the Ca up or down until you get the internode spacing you want on your different strains.
Fe
How's your veg going?

What ppm of Mg is low enough to not interfere w Ca uptake, but high enough to avoid deficiencies? I haven't been using Jacks Part B for some time, since I found generic CalNit for $22/50 lbs at the local grow store. The generic part B doesn't contain any micronutrients, however the Jacks Part A does.
I ordered 2 products off amazon, Jackpot Micronutrient, a chelated microelement supplement, and Microgenics, a similar microelement supplement that I plan to use as a foliar, roughly about $20 each. What products do you use if any?
