@growdoctordc, being high in a certain element doesn't mean you or the plants can use that element in all or in same cases any form

@bobo420, vegetable peelings of carrots, potatoes, and other root veggies high in K steep as a tea. I dilute that at least 1:5 tea/h2o and the plants love it. The sugar can draw tiny gnats of some kind, but they are neither plentiful nor bothersome. The recycling nature appeals also. We have similar nutritional needs as plants - just a way different way of digesting/uptaking!

@bobo420, I have read it on different forums. I would measure it if I could. :)

@Jaindoh, Hi! Thank you for your comments! This is grown under a 30W LED, but I just added a picture from the ones which grown pure on windowsill, and this is not so promising.
