Hello, pretty new to this gardening stuff and looking for advice! I've been growing a basil plant in a pot, and have noticed that it seems to be droopy (although it then perks back up again), the leaves nearer the base are yellowish, various leaves have developed brownish marks at their tip, and there is a black/brown mark on one if the stems, near the base.
Could this be a fusarium fungus problem? If so can I cure the plant somehow, or do I just bin it? Also not sure if it's safe to harvest the leaves?
Or is it something else entirely?
TIA
