Not exactly sure of the pot size just round plastic pots maybe holding approx 3/4- one full gallon roughly, I dont think its the strain as all are fem lemon skunk so I dont really think one would be doing that and none of the others really, not trying to dispute it just dont see how it could be.. Also as for overwatering we only water like every 3rd day and never enough to create runoff and the others have been watered the exact same amount and times as the one that is clawing.. We are using an HID fixture so usually by the third day they are dried out enough and showing that they need water.. Sorry I'm not trying to argue with you, as I really do appreciate the advice, I just dont really get how it could be either one of these problems..
