my plants have been in flowering for about 7 weeks now. i have a problem with one of the plants. i dont have a camera to take pictures of the plant but the buds are turning a nasty brownish color and have a nasty smell as well. can someone tell me if this is bud rot and if i should just throw the plant out? only the main cola and some of the bigger buds are turning this way. if someone has a picture of bud rot they can show me please do.
