Hi, It looks like some normal yellowing from going to flower and just having less nitrogen in the first pic but then it also looks pretty crappy in the lower leaves in the last pic. So here are some possibilities: The soil is staying too wet and not drying enough between waterings (common!) Dry the 'root zone' half way out before watering each time.
Your possibly applying too much fertilizer and it's causing nutrient salt burn (don't feed every watering eh?) Don't use ferts full strength until you have an idea how well the plants like them. (the flushing may help)
The pH of your soil has gotten out of balance because of one of the above or some other crazy 'grow fast' miracle in a bottle substitute for basic gardening knowledge.
Lousy air circulation and venting causing humidity at some point (when you're not expecting it) that attracts fungi.
Little story...I had my vent fan set to go on at 75 degreesF. In winter the closet temps stayed at or below 75 at night and so the vent fan didn't come on at night while I was sleeping because the temps were too low. Daytime no problem with the light on, it warmed up enough to turn the vent fan on. It appeared that the humidity was fine...as long as I checked it during the day. I finally caught a clue and took a flash light late at night and noted the vent was off, the humidity was sky high and temps were low. I was inviting fungus and eventually got Powdery mildew. Just a 'what if' The awful looking leaves remind me of fungus attacked leaves. Anyway good luck!
