no discoloration of the leafs. And its so weird. its just the budding leafs not the fan leafs that are curling.

Sometimes I wait till the plants wilt a bit due to lack of water. then i water. so im pretty sure its not overwatering. But I will do that again this watering. wait till they are wilting slightly then water.

u.g.u

our plants look a bit different. ur fans are curling too and they are discolored. my fans are fine, and everything is a healthy mid-deep green. But I will not fert for another watering just in case.



Great replys thx all. Anyone else have any plants like this or any clue whats up? Ill post more pics tommorow :thumbsup:

i had this same problem and jus put it down to high humidity/over watering. but could this same problem be caused by a lack of oxygen in the water?
