i see a HUGE problem with those containers...

They're white, and not very opaque. Roots HATE light! spray paint those containers black or cover em up or something...

I don't think that's the source of your "funky leaves" but it certainly was a red flag to me when i first saw your pictures.

The leaves looked burnt, but it could also be a bug...

Happy hunting i guess.. keep us posted.

BUT COVER UP THOSE POTS
