What are you feeding? Just cal/mag?
If you dont have any get some proper base nutes & start feeding them. Throw the cal/mag away, If you think they are showing a cal/mag deficiency it’s because you haven’t been feeding them any but that doesn’t mean thats all they need. More than likely have calcium toxicity now, look it up. Flush & feed quality base nutes which will have all the cal/mag you’ll need
