Late to this party, but looking good! I would up that to at least 6-8ml per gallon on the cal/mag! Maybe up your bloom ph to 5.85-5.90 and check em. Phosphorus tends to lock out too in bloom a bit and gives almost the same signs as early cal/mag symptoms. Not the end of the world and should yield you some good smoke! Keep rockin, there is a little learning curve to the autopots, but one of the most easiest growing I have ever done!

the 2 most likely causes of spotted leaves are over feeding, or ph is too low
