Super Lemon Haze Autoflower - Batch 01

Last week! So I'm not risking it any longer, I'm going to harvest later this week. Conditions are getting colder, plants taking less water ( sign of ready in some plants ), I have flushed with 10L water over 2 days to force nutrients out. I also haven't use nutrients for around 10 days now. All plants look different and I've googled the weird bud and inspected it, the bud looks healthy ish just the leaves are dead making it very yellow.. unless someone knows else? Dragoon the black spotty plant is also checked and I believe still to smoke. The colouring is actually getting better and more healthy. I think I had mildew on it last week when we had a storm outside but I cut and cleaned straight away.
