You made a base supersoil to be supplemented with guano kelp tea, 100% of the container should be that soil.... call came in... be back
Its hotter than "roots" which is subs soil base, but its not as hot as subs finished soil. First of all I like doing this because I love making teas (you can supplement with any ferts though, def not full strength) but I dont have to worry about burning younger or more sensitive plants with it. I pop my s33ds in small cells (like the flats of veggie plants you see for sale) with seed mix and castings,,, then about a week later they go into party cups with this mix straight up with no issues.
Just water, tea, and molasses from then on to harvest. Iv taken sample buds around week 5-6 right when and after my tea use is its heaviest and even with a quick dry the smoke was very smooth, flavorful, and the ash came out pure white... Something to ponder on eh. Even with that though I still like to slow down with the tea towards the end, I want some natural fading and finishing.
Damn, see what happens when I drink coffee
Anyway, this is just what Iv been doing. I hope it works as well for you as it does for me.
