My plants are doing pretty good and about 10" tall on 24 hr light. I burned them once with only 1/4 strength Shultz - so I wont use that again - I had to flush & lost some bottom leaves. It's been a couple weeks since and I bought some of the Bio Nova Supersoil and superbloom for nutrients. it should be more friendly for my plants. I watered them yesterday with only 1/4 strength. Has anybody used this product and can I get it up to full strength? The label says 4 t/gal twice a week....but - I figure if I do it every other water ? Will it burn em? My soil is mostly Promix, with some humus/manure and extra perlite. --- Thanks for help.
