it could still be overwatering if the pots are large and they are not drying out almost completely between waterings.

when asking about a plant problem the more info you give the better people can help you. i consider the following need to know information to diagnos a problem correctly.


grow space?
hydro or soil? set-up?pot size?
soil?type?amendments?
lighting? distance from tops?
ventillation/circulation?
temps?
clone or seed?
lighting schedule?
age?
strain?
watering? how often? how do you know when to water?
nutes?ph? what and how often?
any other useful info about problem
and of course pics are great.

if i forgot anything, feel free to add to the list.

i hope this helps.

i know it's not an aswwer to your problem, but if you give all that info it is more likely someone will be ablle to give you the right advice.

anyone else with plant probs should be sure to include that info as well when seeking advice.
