i have never seen this before. only one plant is affected, but it's thoroughly covered! it looks like it's been going on for a while because the tumors start out green then harden and turn brown.
i haven't touched any of them, i'm pretty positive the plant is male anyways so i'm going to trash it soon, maybe i'll dissect some of the lumps when i go to toss it
i ended up just culling the plant, it was a male anyways, and all the branches that had tumors also had fucked up leaves.. i think there was some systemic fungal infection or something
the images in the first post are full sized, only 300x400 pixels
i conducted an autopsy on the plant before tossing it and peeling the skin from the lumps revealed regular looking stalk fibre underneath. in this image the bottom is a peeled tumor and above it is normal stalk for comparison.
