If you are worried that you have over fed your plants and are experiencing nutrient burn, you probably don’t want to just add CalMag into the mix. Most brands of CalMag that I have come across, have additional Nitrogen added into the mix and I don’t think a lack of Nitrogen is your issue. Based on your pics, there are no obvious signs of a Calcium/Magnesium deficiency so adding CalMag into your feed would most likely make your possible nutrient burn worse. I have used the Advanced Nutrient line before with many of my auto’s and very rarely fed above half strength nutes throughout the grow. I see that you are using them full strength with all the extra’s (big bud, bud candy, etc) and that’s alot of food for small/medium sized auto’s. Consider a good flush of the medium with PH’d water, cut back on the nutes a bit and relax. Your plants look pretty good overall and keep in mind that yellow tips are usually the 1st indication from your plant that you’ve reached the plant’s limit. She’s still healthy but she’s got everything she needs- she’s almost red lining so you can’t push her any further. Just my opinion, hope it helps!
