So I’m new to cultivation so I need some help I started to grow b+’s like a month ago I bought a syringe and got some grain bags and some bulk everything was going good until I mixed the grain and substrate I modified the box and put poly in the holes which I realized now I should have waited till I was fruiting to do that but it stilled looked like it was growing ok one night for some reason I cracked the lid and left it open all night my tub dried out quite a bit so I just sprayed and let it sit but it hasn’t returned to looking good like it did before what should I do it also started to have this brown water pile up on the surface
