Don't know the issue but you're gonna love the smoke.

i know its frostin up nicely and smells like some lemon funk.idk whats going on my other grows went smooth but i was using chemical nutes. i figured id change it up now i gotta really know my shit the chems are easy for the most part.i think using these organic lines are a lil more advanced. thinking about trying out the subcool super soil next.

Appears to have a light case of leaf rust. They look fine. I've been growing RP Kandy for the last 2 years. Awesome plant and smoke.
