I’m trying buildabloom from build a soil this year. What Azoetrope says may be true, but throwing on something that is amino based and chelates available nutrients makes me feel better.
Was thinking of steeping some wood ash in water and pouring off the water as a fertilizer... Should be soluble potash, but i do t know if that's caustic potash or sulfate potash?
I have no vested interest in pushing a method but last few grows I have used aerated tea with either high N or high P guano mixed 50/50 with fresh EWC and a couple spoons of molasses bubbled with a fish tank aerator. I only make a gallon at a time and use the high N mix once about a week after flip still and then the high P about every 7-10 days thru week 6-8 depending on how they look by week 8. Sativia types for me are 75 days plus more or less and last two weeks they dont get tea just the liquid fish fert. Plus some epsom and biomin all the way thru from couple weeks after flip a few times.
Im no expert but my plants seem to do better with the tea. I do agree less is more but there has to be more than just the soil IMO if your in 5 gal or less pots. And thats exactly worth what you paid for it.
I'm in 5 gal and it works fine, I only feed the tea 5 weeks out of a 9 week flowering cycle, plain water first and last 2 weeks, I also use chlorinated municipal tap water, it's primarily genetics that impact how a plant will perform
