Algae question

So I've had these random brown spots for a few days. They seem to be increasing in number and just wanted to make sure it's not something i need to nip in the bud!

I'm assuming these are the (diatoms) algae bloom I'm waiting for in my cycle but wanted to be sure!

Yep, diatoms.

So 4 days later and I'm in full bloom basically. My nitrites and ammonia and nitrate are perfect( one handing three test tubes is a bad idea dropped my nitrate bottle). If it still tests fine I'll add some cleaners this weekend!
