Nutrient Question, Schultz 20-30-20

I have 2 plants, both 4 weeks old. They are under 92 W. 65k CFLs (4 bulbs, two over each plant, 3 inches above foliage when I went to bed last night) They each have a 23 W. 27k side light, when they get a little bigger, I'll move them to their permanent home (Out of the box, into the closet) where they will be under the above lights + a T12 2 bulb fluorescent light with 2 40 W. 65k Philips tubes. They are in a mix 10% perlite, 60% MG garden soil, and 30% organic compost topsoil, mix is by volume not weight (perlite ways nothing compared to the heavy compost topsoil.) These plants will (hopefully) be my mothers for a perpetual grow, and I'd like to encourage growth for cloning. The light cycle is 18/6, and the grow box keeps the soil temp around 70-80 degrees constant.

Over the weekend I was given some Schultz 20-30-20 plant food. I searched and found a couple references to this, but couldn't find any direct yeas or nays about these nutes. From what I saw, no one really badmouthed it, but, no one really recommended it, either. So, will these nutes work?

Bueller? Bueller?

Ok, so no advice on the Schultz... One other question, with nutes, is the 18/6, 20/4, or 24 hour light cycle best for a bushy plant?

no one? not a single word of advice or knowledge on it?

Why wouldnt they? Use em in low doses to see how the plants respond and go from there.

Depending on your water, you may need to add some calmag. Other than that, schultz should work.
