Clutchanswered grow question 5 years ago A litlle bit won't do too bad but it's not something that any plant can forgive if it keeps going for several weeks. If u see it first time stop with all the nutrients and let her dry out. Then a flush with pure water and after that u can check ur runoff water on PH. Many growers have those burnt tips. I always start very low on nutrients and watch how the plant reacts to it. This year was good with no burns but previous grows had some minor issues.
