Any help with this deficiency? 250w hps in a 5L pot, soil and perlite cx nutrients. I did some research and my closest guess is N or boron Def.

If it happens on the lower/older leaves at the bottom of the plant and crawling upwards then its a nitrogen deficiency yes, but looking at it it has discoloration between the veins which makes me think it might be a calmag imbalance. Looking very good though ^_^

Looks like nitrogen to me. Boron usually has really twisted new growth on top of the color. Iron can sometimes look like it if your PH is off.
