What deficiency causes this?
My Japanese Cress leafs are turning yellow between the veins and one or two leafs look like they are disintegrating betwen the veins ... it's growing pretty well though, but the new leaves have these issues ... I've attached a picture so everyone can see the issue better. I'm assuming this is being caused by some sort of deficiency, but since I'm new to planted tanks I have no idea what I'm missing.
P.S. I'm following Tom Barr's advice on running a non CO2 tank, so weekly I dose 1/2 tsp of Seachem Equilibrium, 1/4 tsp of KNO3, and 1/16 tsp of KH2PO4.
