Shiny Leaves and Yellow Spots

Hi! This is my first time growing. My plants are beautiful and around 4 weeks old. I haven't had any problems until today when i checked on them. One has a fairly large yellow spot with another spot on the three lobed leaves that is shiny and slightly yellowed. My other plant has tiny pale green spots. I did just top them about a week ago. It's still minor, but I want to know if it's something I should start to worry about?? Is it just a sign to start adding nutrients?

Welcome to Riu and growing.
The one spot looks like something dripped on it?

Your looking to closely at your plants!

The yellowish leaves say you should feed a bit, and I don't like the looks of the soil, but I don't think you have anything to worry about there. No promises. Try cleaning the leaves gently with a damp rag and get them (I'm guessing) under bigger brighter and more light, and give them a gentle nutrient solution drinky and they should be fine. Do you have fans in the grow area? Fans are good. Welcome to the best hobby ever.

check your PH, google PH fluctuations and look at the leaves
