yeah i wasnt making light of situation by suggesting mouse because I had issue similiar to this about 3 weeks ago, for almost a week I was get couple rips on leaves..no idea what was causing it...wasnt me being clumbsy as usual,,thats when I looked down and saw it!!!! one lone mouse turd!!! didnt even know I had mice!!! never see them at all..went right over to store and bought me a pack of mouse traps...baited them and set them all up surrounding my container..no way mouse was gonna get to my plant again.....sure enough the very next morning,,,it was in a trap......turning cold where I live and guess they trying to find warm place before winter but I never would believe had mice because never had seen one in my house......it might not be what happened to your plant but it could really be mice messing with it,,,,run search about mice and cannabis....they have wrecked many a grow...little bastards aint getting my babies!!!
