Horse manure is very high in N and charcoal is a good P,K supplement. Manure and charcoal are cheep and should be availible in your area. Local farmers can steer you in the right direction. ask around and you should be fine
Ive had sucess with hydro rush, neptunes harvest, plant sucesse, physan 20, and soil moist (all 100% free no shipping fee). botanicare closed the survey and paying for shipping and is not free so i dont bother with those.
oh yeah how so. ppm is low enough for even seedlings, no nute burn. ever. guarenteed. now dont get me wrong you could bump up the amount you would just have to monator the ppm. and that would require a ppm meter witch not every grower has. i like 800-1000ppm for my outdoor plants and 300-500ppm...
jacks classic is great stuff!! start feeding plants after 2wks old never in the seedling stage. The optimal Jacks classic mixture is 5ML per gallon with 6.3 h20. Super thrive and Botanicare liquid karma are also essential to veg and seedling stage.
