that humidity is too high for sure. you need to move some air through the space. you'll end up with gnats and/or powdery mildew. I doubt that is the cause of the yellowing.

no bugs, right?
copobo Reviewed by copobo on . growing question well since we are new to growing we are having a poroblem and can't seem to figure it out. we have a clone that some of the leaves are turning yellow and dropping down..we are using hydroponics and our levels seem to be spot on...we are thinking that the plants are needing more nitrogen and have added same but the plants still are not improving..especially my banner clone....any ideas for us to look harder at..
