i have a plant that is 6 wks into flowering and all of a sudden its starting to look really bad. first a few leaves where yellowing and dieing, almost no growth and now i'm starting to get leaf tips browning, necrosis in alot of leaves and some malformed growth. right now i'm trying to keep it alive one day at a time just to try and finish her out. i don't know if i can get another 2 wks or so out of her but i'll try. would i be better off letting it die and then harvest??? thank you in advance
