Anytime bro I hate the mean green I was struggling her for damn near forever, anytime you see that same white puffy growth that is out of the ordinary separate it from your other projects asap right now it’s still sort of in it’s early stages which is the best time to throw it out/bury. when it turns green it has started spreading it’s mold spores everywhere and that is when it’s time to yeet that shit into the sun lol but you will get the hang of it soon enough contam is a bitch to deal with in this hobby we have all spent countless hours cleaning contam and restarting but it’s learning experience in this hobby experimentation is experience really and the first taste sweet success after all of the trial error will show you that all the time you put into this hobby was worth it after all. Best of luck friend hope everything works out pm if you ever have any questions I’m new and still struggling and learning too but we can all learn from each other and grow in this hobby that’s what I love about it so much.
