I'm no expert but when I water my plants usualy the water ends up with dirt in it even tho it came from a natural spring in my horse field lol I don't think that having a little. Muddy water will matter as long as its not extremely acidic or basic
(sorry if I seem like a dick head, it's just the way I word stuff, I suck at it lol)
Edit: you cOuld say this year will be my first grow because I got fucked over by animals last year and before that I just helped people grow thier own stuff cuz I knew alot about it from a kid I worked with that had live in Canada for 4 years growing with his uncle indoors and I picked his brain the entire time I worked with him and that's basically how I learned that and watching friends fail fantasticly and lots of reading on rollitup best place to be lol.
