Several leaves have developed spots like this over the last 72 hours. The plant is 26 days old and otherwise seems OK. Any thoughts on what it is? What do do, if anything.
When you water avoid to wet the leaves, the water cause a magnifier effect and is not good because they get damaged.
From what i can see you have some pictures in your diary,whit some wet leaves.
This might be your problem
Good luck 👊🏽🍀
Such spots always make me suspicious, do you perhaps have a picture of the underside of the leaf? Sure, it could be a deficiency, but you should still rule out an infestation...
