I have an autoflowering, diesel x critical mass it was looking lovely for ages but yesterday i opened the cupboard and half of the top colawas brown so i turnedd it round hoped or the best, opened it today and the other side is al brown too. it looks lik its been burnt but im using cfls and theres not much heat coming off them and the other plant is fine! It must be the lights as that was the only thing id changed, i lowered it just a couple of inches so the lower buds could get som light. it wasnt touching the bulbs and a good 3- 4" away. Its only brown on the outside and still green in th middle. It smells a bit funny but its definatly not mouldy. Please help.
