White stuff on soil

Are you using 2 part synthetic nutrients? The white stuff to me looks like salts from your feed, you get this when combinding a part A and part B together.

The green is certainly algae like. This is down to moisture/shade and light in the room. Scrape it off as dweller has mentioned

Do you feed them molasses ? looks a bit like the remains of it and sugar is a growth stimulator for algae in bright light, that and watering would explain the Mycelium

I am indeed mate, I'll scrape that off now, should I layer my soil with something to reflect the light?

I suppose you could do but I wouldn’t bother tbh. Id make sure there’s plenty of air movement down there and keep giving the top layer of soil a move about to prevent any more developing. If there late veg early flower you could also remove any useless lower foliage or growth that’s shading your pots

Honestly looks like mold and algae from overwatering. Make sure you are giving multiple days between feeds. Mine are 1 and 2 months old and they both go through about 2.5 L every 4 days. Water until you yet run off and then wait until shes dry about and inch down. Because if you keep this up, I promise you, you will get fungus gnats. And I promise you, you will hate your life for it. I've been there, it sucks, avoid it at all costs. If you see tiny black buggers flying around your plants, it's already too late 😰

And yeah I was advised to scrap off the top bit as well. Just scrap some off and replace it, letting her dry out properly, and you should be golden in no time

if you are using synthetic/chemical nutes then id find out if its worth using molasses,im unsure if theres any benefit unless youre doing organic grows.

redsiel will likely know
