You definitely need a soil change. The symptoms you have described are too general for me to figure out what it is, though. Try working through it with Doctor Optimara (link)

Thanks fuzzyleaves. I checked Dr. Optimara and there are so many things it could be, I can't determine anything. It seemed to have spread between plants and is more affecting the lighter leaved AV. The darker leaved ones don't have it as bad.

I would go with the obvious before other things....these plants desperately need repotting! If the roots look healthy and no signs of pests, that may do the trick. A year in the same soil is way too long.

Thanks. I've been putting of changing the soil.

I recommend that you change the soil out every 5-7 months - sometimes sooner if the pot is smaller.

You definitely need a repotting session :)
