What kind of medium are you growing in? Nutrients used? Growing conditions? Also this should probably be in Plant Problems forum.

It's an easy fix, your have a calcium/magnesium deficiency. Grab some Cal/Mag from your hydro store, or google CalMag alternatives for home made solutions. It'll take about a week to go appear to be better, just focus on the new growth of the plant being healthy not the old leaves that have the unhealthy spots.

A looks like Phosphorous deficiency in veg, B looks like Cal/Mg deficiency or nute burn.
