sorry to see that man, ususally a plant will do that in the last week of harvest because its uses lots of energy to make flowers, thus resulting in a slightly yellower or less-healthy leaves. But that looks way too early for that, i'd say it's some kind of defficiency. not sure which though cus i'm not an expert however i saw a similar problem in s12 fever's growlog ang he used a banana peel on the soil (don't worry, no harm can come from it, but if the peel starts to turn brown within 24 hours then she's taking in the mg/potassium she was possibly lacking, i'd just try it for a day :thumbsup: )

keep it going though man, even if it gets worse, you'll still have some kind of cola to look foward to.

also, how wide is your plant man (like at the widest point), i'm dying to know cus mine seems pretty damn wide (10 inches...) and i'm running outta room if it continues expanding this rapidly for a couple more week...
