Can I cut back dosing a bit? TDS is @ 500ppm

Hello, about 3 weeks ago I finally got my CO2 working and I started to inject CO2 at about 30ppm and dose EI according to the calculation done by rota.la. I do weekly 50% water changes as well.

My exact parameters:
29 gallon tank
2 24" T5HO bulbs from Odyssea light fixture

TAP WATER:
pH 8.0
dGH & dKH around 12
TDS 289 ppm

AQUARIUM WATER:
pH 7.0 with CO2
TDS is now hovering around 489ppm.

FISH I TAKE CARE OF:
9 total Gasteropelecus sternicla and Thoracocharax stellatus (Common/Silver Hatchetfish)
About 12 Otocinclus (I think )
3 adult bronze cories and their 25 or so babies
Probably around 30 cherry shrimp

Tank is MEDIUM density planted. Plants are currently in "grow out" phase and I don't want to pay up in order to get more of them. I'm thinking this is what is causing the accumulation of chemicals.

Fish are all happy and seem normal, but I know they are all Amazon fish who probably aren't used to a TDS of 500ppm (except for the bronze cories who have probably been bred in local water so many times and the cherry shrimp)

So, question is. Can I follow a loose EI schedule? Instead of Macro M, W, F and Micro Tu, Thu, can I cut that down?

You can cut down on dosing as long as the plants don't run out of nutrients. Although I'm not sure that it will make a huge difference in your tds since your tap water is almost 300ppm. If the fish, shrimp and plants are happy why change anything?
