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.

Thanks,
Harry

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.

I'm having a similar issue, going to switch to TMG (plant nutrition) for the Mg & Ca, does Seachem have those in the product you are using?

NOTE: To do a *SEARCH* and get the answer you want, its often best to go to "Advanced Search" and search in the title only.

Seachem Equilibrium apparently has Fe, Mn as well as Ca/K/Mg/SO4.

Cardamine lyrata likes cooler temperatures, and CO2... Possible that it doesn't like the conditions in your tank. Are you dosing some micros besides the Equilibrium? Small doses of Flourish help if there are things missing in your tap water.

How small of a dose are we talking about ... ironically I do have Flourish on hand, just am not using it cause Tom's method doesn't call for it ...

Btw, this is a 55G tank.

Thanks,
Harry
