Hi soorry for asking again but my plants are not prealing anymore!!

At first after dosing seachem equliblium (GH) as per Tom's advice it started to peral for about one week.But then in the weeks to follow there was no peraling at all. I added i think an too high level of dry ferts and all my malayan shrimps died .
I think it is the improper amounts of dry ferts i add.

Tank 1 feet by 1 feet by 1 feet =about 7 gallons
lights are fine 21 watts
co2 is fine about 22ppm

dosing
Required levels of nutrients
CO2 range 25-35ppm
NO3 range 5-30ppm
K+ range 10-30ppm
PO4 range 1.0-3.0 ppm
Fe 0.2-0.5ppm or higher (?)
GH range 3 degrees ~ 50ppm or higher

Fertillizers used and level provided
Lushgrow micros 1 ml
0.7 iron
lushgrow aqua 5ml
0.3 iron
9.1 potassium
5.6 nitrate
1.3 nitrogen

0.8 teasppon of kno3
0,2 teaspoon of kh2po4
4.2 teaspoons of kso4
7 teaspoons seachem equlibirlum
in 100 ml of water dose about 5 ml three times a week

Can anyone tell me how much to dose dry dosing preferredand when (eg a dosing scheldue that works for u) cause I have been experimenting for a week readin the forums and Ei as well as online fert calulators like fert friend or chuck's aquarium calculators and i can't seem to get it right. (the first time it peraled was when i randomly threw it 1/16 teaspoon of each dry fert and liquid fert)
