I use 1 -2 gallon pots currently for Auto's with the supersoil.
I add cal-mag pretty frequently, a little Liquid Karma here and there, and some sweet or molasses.
Beneficial teas I also use to keep the soil live and active. (EWC,Ancient Forest,Molasses,Mycogrow Soluble,) and either a bit of maxicrop or cytoplus sometimes)
If early yellowing starts, some fishtank water, or a topping of superoil, or a tea with alfalfa meal, or 1-2 feedings of Nature Nectars (5-0-0) Nitrogen works for me. These are for the heavy feeders.
I also use Hygrozyme from time to time, and HP2 for my bud booster. Remember auto's are sensitive to nutes.
With the new recipe for this year he has, I doubt that cal-mag should be an issue in the future with the slight changes and additions he made.
Ammending with tea's should get you buy, I would do it all the time and save on the other nutes, but I cannot always make the tea's at this time
so a quick solution mix I of the additives I have works for now.
To be honest cal-mag and maybe a topping of soil later for me would get me buy, but I push my girls a bit and they like it. I run a 10 week from seed to harvest auto Snowryder (f) x Russian Rocket Fuel (m), start flush at 8 weeks, harvest at 10 weeks with white ash clean tasty smoke after the proper dry and cure. All done in a closet under t-5's 420 watts total Avg. 3/4-1 oz. per 1 gallon, 2-2.5 oz. per 2 gallon. 1/2 lb.+ per harvest due to 6 plant legal limit. Easily could get more if license permitted. $20-$25 month electricity used.
All in all very happy with the results very crystally, potent, tasty, and higher than avg. yields per strain quote on seed bank info.
I can't wait to get back into bigger pots and space to run some tga strains in some supersoil the way it was ment to be used.
P.S.
He's finally got a mix coming out soon called The Green Avenger (supersoil flower base) used with Down To Earth's Pro Organic Mix as the top mix, it was on his last tube show where he talks about it, posted last night.
Here are a few photo's, had some heat issues, someone kept turning the heater up.
