What am I lacking nutrient wise?

I'm using EI method for dosing dry ferts. Mainly Kno3 khpo4 and Plantex +b. I've been testing my nitrates and phosphates with nutrifin test kits. Nitrate is a little hardbut it's somewhere between 10 and 20 ppm. Phosphates are between 1-2ppm. Dont have an iron test kit anymore. And CO2 wise I have about .8 ph drop using a digital controller with pressurized co2

My sword plants have brown spots forming in both old growth and new growth. It's growing tons of new leaves, though they are a bit shorter than they used to be since i started this new tank. Dosing the same way i used too, but now I"m getting trouble.photo 2 [145955].jpg

Are these plants from another tank? How long ago did you put them in tank? From my expirence I transferred anubias Nana to a new tank and the leaves began to not do so well and die off. The new shoots came in looking great. Maybe adjusting to the new water quality??

MY 70 gal sprung a leak and I replaced with a 90. Same plants from previous tank. Same substrate too. They've been in this tank now for about 6 weeks.
