Help :( some kind of mold/fungus? (pics)

Hey all, just thought things were picking up with my yellowing problems and now im getting these weird spots on her they seem to be spreading around the lower older leaves that were original to the clone and all new growth is ok so far.

Ive picked off the older leaves with the infection as they arnt getting any light anyway.

thats not mold at least i cant really tell but normally you only get mold on buds but how much water do you use and how often?
