That's what I'm guessing, come real growth time the much more vast root system should kick butt over plant B. The soil is just Black Gold seedling mix with extra perlite, bat guano, worm castings, Azomite, and Myco's. I am using Nectar For The Gods Greek Regimen (first feed was today at 1/4 strength) from Oregon's Only. Plant A is getting their Kraken foliar spray up until stretch, roughly, depending on how many pre-flowers there are and how closely stacked they are on top of each other, and Bloom Khaos foliar spray as well starting in another week or so. The Kraken is a Shrimp Shell and Crab Shell 0-4-0 foliar and soil fertilizer that also has an egg protein in it, you should check it out. Bloom Khaos is a 0-0-0.5 kelp meal foliar and soil drench fertilizer. I am using both at full bottle strength per quart of distilled water, PH'ed at 6.4, the left overs are going on my tomatoes and peppers and both are responding beautifully. I know there are a ton of fert's out there, but this one is close to home and not quite 100% Organic, but not loaded with salt and BS, I have high hopes!
