Sometimes plants will swell at the nodes and look sort of like a knuckle. I wouldn't be too worried as long as the plant is healthy. Edit: IME I see this happen mostly when I top a plant. Sent from my iPhone using Grasscity Forum
It's nothing. Obviously, you're working with a female plant. Unless you stress it badly or screw up it's light cycle, shouldn't have to worry about seed production if that's your thought. Stop being paranoid and let the plant do it's thing. Keep your grow simple and this keeps you more stress free. LOL Best of luck. TWW
It's literally just to help hold the weight of the branch. It's like a natural strap to hold it up. Sent from my SM-G930W8 using Tapatalk
