Calcium and potassium interact with each other and require a balancing act to work well in a plant. You can't overload a plant with one element without locking out the other.
Calcium is the engine for metabolism in the plant. It is required mostly in transition to flower. The most common source is calcium nitrate, but that is the easiest way to throw off the nitrogen balance in the plant, especially in flower. Calcium imbalance can be caused by incorrect pH, improper watering, or nutrient imbalance. In soil, it can be fixed with gypsum, lime, bone meal or compost. In hydroponics and foliar use, I prefer supplementing with calcium acetate or amino chelated calcium at transition.
Take a look at the available ppm requirements of calcium from Agrien tissue samples at the different stages of plant growth in cannabis:
Potassium is for all around health and water balance for the plant. It is required mostly in late flower. It is very easy to overload a plant with potassium in coco coir, by adding things like kelp, or potassium sulfate. Potassium deficiency can be caused by incorrect pH, excessively dry soil or nutrient imbalance.

Always do testing to help correct any issues in the root zone with a pH meter or soil test. Issues can always be minimized by starting with a high quality potting mix or balanced synthetic or organic fertilizer.
