If i had to guess based on the pics alone i would say ur over fertilizing them, and if mold is an issue u need to drop the humidity, it will only become worse of a problem when buds start to really form. U need to fill out the form and also include how often u change the res water.
JackdaWack Reviewed by JackdaWack on . Is this something to worry about? Ok I'm in the 5th week of flowering some of the leaves have mold very few of them. (see pictures) Some of the leaves more than a few seem like the edges are burnt and the tips are curling. (see pictures) Whats the cause of these things and is it soemthing to worry about? thanxs Rating: 5
