What Deficiency Might Be..

I have this Ammannia praetermissa from dennerle. i got this plant all red. The new leaves coming green but I think is beacause of my nitrates are high ( don'thave problem with this). My problem is the new leaves show some darker colour on the edges. Can you recognize if I have any deficiency??
(Also check the R. macrandra for deficiency)

 

yes probably I need more ferts. I don't know my par but in 300Lt tank, I have 4 T5x39W with reflectors. My Co2 is drops 1.3 from 7.4 to 6.1 PH.
I believe I must pump my fertilizers because I change 50% once a week. Maybe is more easy to see toxicities and fix them, than deficiencys.

 

My tank is running for two years. I did many adjustments with my CO2 and I believe I am in good target right now. As for the lights, I think is good 160W with two white and two pink lamps.
I m sure I have deficiencys beacause my rotala macrandra next to this plant is growing very fast but the old leaves have many holes except for the upper part which is great.

 

I add weekly
NO3 = 11 ppm in 3 doses
PO4 = 4.5 ppm in 3 doses
K = 9 ppm from the two above.
I raised my CSM+B dose a week ago.
Fe= 0.35 ppm in three doses.
Mn = 0.09 ppm
B = 0.063 ppm
Zn = 0.027 ppm
Cu = 0.0044 ppm
Mo = 0.0027 ppm
With the water of change I add
Mg = 12ppm
Ca = 33 ppm
KH = 2
Before I found out I had Mg = 33 ppm and
Ca= 15 ppm
values in the water column before water change
NO3= 35 ppm
PO4=2 ppm
Fe= 0.2 ppm
K = 25 ppm
values after water change
NO3= 20 ppm
PO4 = 0.5 ppm
Fe = 0.05 ppm
K = 20 ppm (this is strange).
All with JBL test kits

 

these days I have some GSA on my plants blades. And my rotala macrandra has a problem with old leaves.
