Good info DTOM! I just got my KIS Nute Pack on Friday, soil mixing this week -
technically that's the deal, provided you follow instructions on pot size... also look into their tips for better harvest, supplements that help it all come together better and yield more with minimal inputs... They suggest inoculant/tea to support and boost the soil herd, critical for top performance in organics; Si, kelp, humic-fulvic are major players in keeping nutes available, uptake/metabolism.... And a little PK boosting during bloom will make the buds even fatter, better quality. You can top dress with something, or water-in... Last year I tried Roots Organic Terp Tea Bloom, very fine powder so it waters in easily, and it performed well!
So, if you want to put a little more effort and goods into the "water only" gig, it pays dividends! PK
can get depleted later in the grow, at the time when demand is highest so a bit of occasional boosting makes more and better product...
