Here's my run down...

I wouldn't sweat it unless it spreads/appears on other plants.

Cool... Not really worried as much as I am interested. Lol. I read something about black spot fungus but it's described as a black spot with a yellow ring around the outside of the spot. Clearly not my case but it's all I could find

Very good airflow... Practically a completely open area with 3 windows creating wonderful cross circulation. Windows stay open, screens with absolutely no damage or reveals where they butt up against the window opening itself. 1 oscillating fan floor level... Believe me when I say the airflow is more than efficient... Helps to keep my room temps down

I even play my girls reggae music all day... They seem to like it!

I do have a single AK 47 seed that popped but once it grew it's first set of leaves it seems to just stay the same size and the plant leaves looks all mutated... Something I have never seen before and I've ran my fair share of grows. Oh well I guess it just wasn't meant to be lol. Time to toss it and start a new strain... The question is...

Blueberry Punch
GrapeGum
or
Strawberry Sour Desiel
