(First time posting to this sub, first year growing plants.)
Recently, about three or four weeks ago, I purchased a small Oregano plant and potted it in a terracotta pot. Through doing research and talking to people I know that plant annually I purchased the plant nutrients/fertilizer I would also need (I follow the directions to the letter to ensure I do not over-fertilize my plants), and I also found a spot in my house with ample sunlight to ensure they get the amount of daily hours they need. However my Oregano is the only one of my three plants (the other two being Lemon Thyme and Lavender) that is having issues.
There are small brown bumps on the bottom of my matured leaves and it is spreading to the smaller sprouts, these spots begin to make yellow ringed burns on my leaves (and there are a little on the stems now too). One of the stems in particular concerns me because it has begun rapidly wilting. I fear my plant is diseased and I will have to get rid of it, is that the case? Or can I save my herb plant?

Does it look like this? If so bacteria may be and issue. I get nute burn sometimes that can look like that. You mentioned potting them up into terracota. Is the soil you used pre-treated with ferts and ad mixes? If so adding additional fertilizers may be causing burn. Trim the affected leaves back and try a light misting of the remaining plant. Good luck and thanks for posting.
