looks like too much nutes. i could be wrong.

could be they are sensitive plants and full strength nutes are too strong, try them at half strength it might help them out? i use biobizz nutes and at most feed 3/4 strength they recommend, in my experience the plants would just get burnt feeding them full srength..... (i think they state that much on the bottle to get you to use more, so you have to buy more!!!!)

Ok, guys thanks a lot i was thinking it was to many nutes but it didnt make much sence with the fan leafs beeing yellowish colors...naturally they go yellowish but id have thought for them to green up a little if it was the problem, i watered them without nutes this time, see what it does.
