Spots on upper leaves

Was gone for a few days and came back to see this on the upper leaves. They were rather close to the light - i had to raise it. Is this due to the light or something else?

Running a Mars Hydro TSW2000 in a 3x3
DWC with Maxibloom and added about a tablespoon of epsom salt to the 5 gallon bucket (thought it might help i dunnoh). Any help would be
much appreciated!

Thanks for the response - i figured it might be because of the light but i was also wondering if its septoria - im a n00b so i thought i'd run it past more experienced people

Thanks again!
