Damn..

Ok do your plants have fresh air? I see that you dont have an exhaust fan... plants need "new" fresh air to thrive.

Also you need a way to check and adjust your PH. It can be hell to try and grow without being able to control the ph.

I dont do the whole foliar feed thing but if you are spraying your plants right before bed it will cause a big spike in overnight humidity, which can lead to nasty things such as evil bud rot.

Also your temps are a bit cool. Try getting them up to around 75F for better results.
