I am definitely gonna have to try this! I've been wanting to switch to organics, it's actually part of what I have in mind for Grow #3 except I don't have the air stones or anything. I'm thinking of going to a DWC system (Tax Time Baby!!!) but wanted to get it all at once. Is there another way to make the tea without the air stone? I figure I have between 3 1/2 to 4 1/2 weeks left before harvest. So far the def is only in the lower fan leaves, it hasn't affected the upper leaves or the branch leaves. The top cola has two sets of leaves on the very top that are turning into claws, no scorching or discoloration. It can't be heat because the Special Kush is taller and closer to the light and doesn't have any claws. Still learning but for only my 2nd grow, I gotta say I'm pretty happy I just wonder what the yield is gonna be, I'd say most of the buds on all three are about the width of C battery and as tall as an AA battery. It doesn't seem like they are growing much, but I look at them so much I probably just don't notice them growing.
