If it is just a couple hre and there it might be bugs curling up under them laying eggs.. or if they are in pots then they need more room for the roots maybe.
pugimo Reviewed by pugimo on . PLZ help... i searched... ok, at first it was only one leaf, but now its happening to ALL my new growth! The sides of my leaves are curling DOWNward and i dont know what to do... I water every two days and only when the soil is dry. I think it may be a Mg deficiency. What is an easy way to feed it Magnesium? Thanks Rating: 5
