ok so ive been growing for just about 2 years and i have never had a problem besides my genetics were a little airy so i never got the most dense buds but everything always looked great smelled great and smoked great. recently i started a small 8 plant grow with my roomate the first batch was fine but sum of the 2nd batch about 2 weeks before flowering started to almost burn itself. like it wasnt burnt from heat but most of the leaves and some of the actual calyx would turn like a yellow orangish color(looking kind of burnt) anyways my room is at 75 degrees F and the humidity is around 20-25rh. my buddy thinks the humidity is too low and the air cooled lights are causing the buds to get almost wind chapped. this is the first time ive used the nutes we are giving them but my buddy had to go organic so we feed them every two watering ie feed, water, wate, feed.hes responsible for the watering so my whole thought is that the problem lies in the nutes im thinking he is skipping days and in turn the plants arent getting enough nutrients to flower normally. if anyone could please chime in id appreciate it greatly. Im two weeks into flowering on my next batch and would absolutely hate to see this again
