So I’m 39days into flower I went away for 4 days I had my brother look after plants I came back and all hairs are brown look burnt only the top of the top buds are like this. He said he sprayed some safers 3 in 1 but I doubt that would do this? Could they be burnt from sprayed during lights on Or could it have been a hiding nanner popped and pollinated? Any input would be appreciated thanks
