I am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?

Measure your pH, organic nutes are less stable than conventional nutes. Keep in mind that a bad pH will change which nutrients are available to the plant causing all sorts of problems. At the very least, get .1 test strip. They're cheap and last forever. Calmag tends to buildup in coco, so it's a good idea to skip it occasionally.

I would at least try either a 1 ml every other day or .5 ml a day. If you have a soil ph tester I would use it. Ph being off will cause problems. Coco coir absorbs calcium and magnesium. Great for aeration. So additional is needed to compensate.
