Difficult to see what the plant is showing without true color. If the leaves are infact yellow look at Ph as it screws up everything. Wouldn't expect N, but I've been surprised sometimes. Have you checked the soil Ph or the outflow? Depending on the soil and nutes, amending the Ph before watering may push the needle too far.
