Sugar Leaves Turning Yellow

Sugar leaves around top colas have started to turn yellow? No yellowing on any fan leaves. Plants are same distance to light and the environment has stayed constant. Only changed feeding cycle from alternating feeding/watering to feeding,feeding,watering (ppm still the same).

Could be a CalMag issue, early sign. Are you giving the plant enough calcium and magnesium? I would suggest 100-200ppm per feed.

Thanks for your reply. I have been supplementing with CalMag on feeding as well as watering days from the beginning.
