Fritz turbostart brown circles

Anybody know what these brown circles are on my glass and rocks? I'm 5 days into cycling my new 90G. I'm using Fritz Turbostart and Nitrocycle as the ammonia source.

A photo under white light would be better for an ID.

It’s probably diatoms or something. The same thing happens to me every time i cycle a new tank.

You have your lights on and you have added nutrients (nitrocycle). Lights plus nutrients equals algae.

Thanks. I'm overreacting. I didn't get these during my prior 2 cycles so got a little concerned. I turned off the lights until the tank is cycled.
