Defficency in Non-CO2 Low light plants

I replanted a 20 gallon that I have had for 8 years now. I wanted to try the low maintenance (no water changes, no CO2) method discussed elsewhere on this site. Last week I planted several crypt types, a marble sword, blyxia, a chain sword, corkscrew vals, green temple, java fern, java moss anda few anubias. It has a red flourite substrate that has been there a long time. It has 2 t-5 14 watt lamps (Coralife Freshwater Aqualight) Even though it has only been going a week I started the suggested dosing (1/4 tsp of SeaChem EQ, 1/8 tsp of KNO3 & 1/32 tsp of KH2PO4 per 20 US Gal tank.) I know my water in NYC is very soft. So far I have only dosed once.

The new leaves of the vallsinaria are short more twisted than the old leaves and the green temple's new leaves look burned and yellow around the edges. I thought it might be boron as none of the water column supplements have it at the moment.

Could this be some trace missing (like boron) or perhaps something more simple like a calcium deficiency? Should I be adding a trace supplement too (like Flourish Trace?) I suppose I should get a test kit to test the Ca, but I was hoping this would be an easy aquarium!
