Gonna go with "not all your grows are gonna be winners". We're starting day 21 of flower in here. Pretty sure I confused myself last week and mixed everything at a half dose like I do for my autos. Some browning on the CP's and the CG have a pretty bad potassium deficiency. Neither are happy with me right now. Did a pretty big flush yesterday and made sure to be careful on my dosage this week and we'll see how they respond. Just need to get them to harvest and we can try again!
