Yellowing and spot...spreading

Ok so autoflower, week 5 of flower, day 77. 2 1000w leds. Temp 77F. Humidity ~50%. 20/4 cycle. Using gh flora series. Micro 5.3ml/gal, gro 5.3, bloom 7.6. Following recommeneded feed schedule. I noticed the problem and asked on here once and the consensus was a manganese deficiency. I started adding 3ml/gal of cal mag plus, which we thought would solve the problem. However it seems to be spreading to the leaves around the budding sites now. Forst grow, any help would be greatly appreciated.
