I think I was overwatering late into cycle and my plants developed these black spots that look suspiciously like black mold in the leaves. It does not seem to be making it to the buds themselves should I be worried?
Concern is warranted; the black spots are already on the green leaves in the pic.I'd remove those affected leaves. Not sure if it's a mold issue or just old fan leaves being being sucked dry of nutes. I'd be more concerned if it was on the green leaves, but certainly keep an eye on it.
I think It is mould or fungal infection,
That's not thrips... If thrips was that bad you would definitely see them everywhere, I don't see a single one in this pic... That looks like his leaf is so soggy it's growing algae or Snuffaluffagus sneezed on itSeems it may be a huge infestation of thrips. The black spots could be poop, and there are silvery patches on some leaves. Get a magnifying glass or jeweler's loupe and look really close for little fast moving bugs on the underside of the leaves. Yikes.
