Mould or something similar on soil

Hi guys,

Its 8th week of flowering, end is near and i just fu...g saw something that looks like mould on top of the soil. What is that and how do I fix this ? Pictures attached

Gsc autoflowers in case that info is important.hesi food, but i stopped feeding them a week ago, only water now

Ignore the pot

What nutrients have you given it lately?

Likely mycelium of some sort. Its eating your nutes, and trying to create balance in your soil.

I get this when I use organic jobes 2-5-3.

I use hesi starter kit...i heard its crap

Me 2, remind me 2 give you an update in 1 week, when my plants have grown a little
