Yellow spot with a tiny hole

under current lighting conditions best guess is a water drop... Does this make sense.. Look in my diary at growing a tree and you will a plant that has external damage to it from water pooled on the leaf. Just a guess hard to tell.

Its a 4 week old Strawberry cheesecake auto by seedsman in miracle grow potting soil with added pearlite, just recently started feeding it open sesame a few days ago as I felt the nutrients in the soil would suffice for its first few weeks. I water weekly though with Ph 6.6 water.

Hi, under the blurple light it's unfortunately a bit difficult to see, and given you don't have a diary, we can't say what medium you grow in, what, how often and how much you feed your plant or any other surrounding information that would be really helpful in trying to help you figure this out.. would it be possible to make a picture in normal light (don't worry, a flash from a camera doesn't harm the plants ;)) happy growing
