Na, they have decent sized pots, not sure whats caused it.did you squeeze em in those spots? sometimes if you squeeze em they form a knot whne they heal
I think Dizzle Frost means, did you squeeze the stems in those spots, not pots
I wouldn't worry about it. Thicker stems support bigger buds, which is always a good thing.
Sounds about right.Hah, didnt read it properly dont think so, couple plants got a little squished when lights fells on them when they where young, so could one of those plants.
