Algae like stuff in medium

[Awg52]

Hi guys, I’ve went up to check the plants this morning and noticed some algae like green stuff on top of the medium, noticed it cos the colour of the perlite looked off. Anyone any ideas why and if I need to worry ?
also my temps sitting between 27/28 degree Celsius, the humidity was sitting at 70% but it’s now dropped to around 47%, I’ve not a lot of space left in the tent for humidifiers etc so anyone any cheap and space saving ideas for boosting humidity?
The girls are now day 12

Nothing to worry about. Just make sure you don't overwater the soil as it seems very wet to me.

A cheap way to temporally raise the humidity is to put a tray with water inside the tent. The more surface area the better.

I just watered them about 1 day ago, with the water tray should I start with warm water or cold wil be fine?

It doesn't matter. I would just use lukewarm water, about the temp of your tent

I like to bottom water after about week three. Keeps the top of soil dry, free from knats and algae.
