Hey guys! Can someone pls tell me what this white stuff is on the top of my soil? I’ve been gone for a week and now some of my plants have this?

Looks like mold—scrap off the moldy soil, dust it with cinnamon (contains an anti-fungal compound), then think about the air flow around the soil (you get mold when it doesn’t drain/evaporate well enough)

I’ve recently started using fertiliser and I use tap water to water them, I was thinking mold tho :( I’m just hoping it’s mineral deposits

Yeah, sorry to break it to you but it’s at least not hard to treat. Just clear off the moldy soil and make sure the plant dries out a little between waterings. I don’t think fertilizer or hard water should leave anything behind, but if you’re concerned about that happening in the future then you should switch to distilled water and dilute the fertilizer
