That's was my thoughtI say overwatering. Looks pretty clearly to be overwatering. Nute burn would involve dark leaves, curling, wilt, etc. This just looks like overwatering leaching away Phosphorus and Potassium.
How often do you water, and how much? Your root system isn't expansive enough to cope with whatever you are doing to water it, either frequency or volume. I say frequency, due to lack of leaf bloat.
