So I'm absolute newbie first grow this year decided to grow outside as sufficient funds were not available to grow indoors, the plant itself is about 16 weeks old around 5 weeks into flowering, it is in organic soil and hadn't had any nutrients up until about 3 weeks ago, growth has increased dramaticly but i have noticed a brown/black/yellowy patch appear on the stem and also some discolouration in some of the lower buds. oh ive also been at war with the spider mites for about 5 or so weeks i have no idea when this thing is likely to finish flowering feels like its been going on forever :/ thoughts and ideas people?
