When you face cal mag problems and your medium is soil, you must never flush so violently because you make it worse. You must add cal mag in the form you choose and lower the water you provide. Calcium is slow to enter the plant but fast to leave the soil. It follows the water to wherever it goes but gravity regulates the speed. So you add cal mag, water less and wait. Adjust your feed after the flush cause your plant has less nutrients available after the flush.
