Live in South; heat index over 100; humidity 90%+; plants about 8-12" tall but just one shoot on all except one. Looked good two weeks ago; now turning brown. They are autoflower fems that were to mature about now. Don't know if I should harvest them now. This is my first time; don't even know the terminology. The little 'node' (balls) were green and now brown like burnt and just fall off when touched. Bud rot???? I need soooo much help!! Thanks.
