Sorry we do not make a cal-mag product, the Leaf Green is a veg foliar spray and is not our cal-mag solution. The reason for this is because Ca and Mg are present in the base feed, and coco has a higher ppm feed than soil to provide the addtional cal-mag.
If extra cal-mag is required past the appropriate ppm range, the lights might have to be raised, Take Root has the most cal-mg besides the base feed, you can try adding a few mls if you are still in veg or any other cal-mag solution can be used, if using another company's cal-mag I just suggest doing it in its own watering and not mixing it directly with Dutchpro to avoid any kind of negative reaction.
Thanks!
