Benzelsanswered grow question 3 years ago Could be a few diff things and good news, none of them are a prob. Could be a bruise from a knock, a scrape mark from something rubbing on it or even just a bit of loose surface skin. Unless you can see a wound and it looks like its bleeding from that then your fine...or its some kind of miner insect we dont have here and ive never seen before- but I seriously doubt that. Dont worry, anything that small wont harm the plant.
