I've been trying to find out what these are and all I can find is everyone keep talking about root bumps. I really don't think that's it cuz it's not just on the bottom of the stems. The're green/clear and when I touch them my fingers get wet, (not really wet just a little) like the're leaking but the liquid just smells like tomatoe plants. The leaves look healthy and the plants nice and green, but it's not setting either. I finally had one flower set and start to bud but then it to fell off. I've had 4 fall off so far. I'm wondering if it's a fungus or since it smells like the plant if maybe it's retaining water? If I can find a camera I'll up load some pics soon.
