Here’s the fun part: you get to play vegetable detective. Brown spots from guttation are dry, tiny, and flat. They look like coffee grounds someone sneezed on a leaf. Totally harmless.
But bad spots are a different story. If the spot is wet, slimy, or has a fuzzy halo—that’s rot. That’s the bok choy telling you, “I’ve given up on life.” Toss that one in the compost bin with a tiny funeral.
Here’s the rule: If it looks like a freckle, eat it. If it looks like a bruise, inspect it. If it smells like a swamp, run.
