Deficiencies ? ..help

Hello all,

Nirvana BlackJack almost a month old, in biobizz lightmix, just repotted and noticed problems on the leaves.
I have been feeding it with every watering with Dynagro Foliage Pro but on a very diluted mix ("Maintenance" suggests 1/4tsp per gallon for every watering). The black spots are on the top leaves closer to the light ..is that a calcium or manganese deficiency ? Also the lower leaves that turn yellow ..is it a magnesium or nitrogen deficiency ... and what have I been doing wrong ? Cheers.

p.s.
some leaves have some soil/dirt on them...its from turning the small pot upside down to repot.

Thats nitrogen deff for sure but cal-mag wouldnt hurt i use it every feeding and if that dont work 3 days later and u dont see any helped it its probly stressed from transfer no biggy nitrogen and cal-mag is what id feed them

would upping the dosage of dynagro help instead of getting an additional product ? Foliage pro has 2% calcium and 0.5% magnesium. Im also using tap water not reverse osmosis ..I reckon it shouldnt be so calmag hungry... ?
