Something wrong with baby tomato
So my first baby tomato was growing fine until I saw it this morning and it had these teeny tiny brown crater like things and these crater things were not there yesterday morning.
I will say that my tomato plant has some yellow leaves on the bottom due to possible problems in the soil, which was store brought. I have this plant in a container. Though I do have to say that the plant doesn't have any major problems that I can see of and so far it has been growing well.
I will be testing the soil soon so if this problem is related to lack or overdose of nutrients it would be helpful.
Thank you for you help and sorry for the crappy pic, my phone camera sucks. (That second pic with the water on the tomato is not cuz I watered it lol, it rained)
