First grow, 2 and a half weeks and yellow spots popped up. What’s that mean ????

Do you spray the plant with anything? I could be wrong but it kind of looks like damage from water spots being left on the leaves.

Check for pest and more info what you growing in ,how often you water

I checked with a bright light under the leaves and dont see any. The plant on the right is the one I’m having trouble with the yello spots. left one was planted the same time but no yellow spots. And ever 3-4 days i water.

i did put a little water on them on an Accident when I was watering. I’m going to wait a could of days to see how things go. Thanks for answering
