Yea, could be too humid, Ga...could be PH, could be the nutes...could be a lot of things...OP, I would post this in the plant problems section...you'll get more responses. If you are giving them nutes straight up by the directions, I have often found this to be way too much for some strains...try lightening up on the nutes a little and go to the plant problems section and fill out the trouble shooting form...We need more than what you've said and the pics to help you! We can't help you much if we don't have enough info!
