Thanks Harry, The temp doesn't seem high, the room temp is high 70s humidity is high40s, I'll put something reflective over the tub to keep res temp lower. They just look a lot smaller and seem to have a lot less leaves than some other plants I've seen here ? PH is low 6s , I was going to wait till after the wkend and change water and try 1/4 nutes. Thanks again for input.
