Brownish/blackish, mushy stuff on leaves

I got 2 ladies 1 1/2 weeks flowering. FF soil, nutes, cfl lighting and everything else looks pretty good except for the slight clawing of the leaves...over nuted a lil, but I saw some brownish mushy spots on one of my girls this mornin.(newer growth) Anyone got any ideas? Ph is like 6.7-6.8. I thought it was heat stress, but like i said, its mushy and there is a spot or two on a couple lower leaves as well.

This was not there AT ALL yesterday. The only thing different is that I added some fans in there. 1 computer fan and a small oscillator. Anything to do with it, maybe?
