no that would not be enough. you will need to inject actual CO2. excel is not a co2 substitue unfortunately.
you will also need high light, flourescent light is not neccessarily the same as high light...
A combination of highlight and CO2 will allow the plants to use the fertilisers.
additionaly you will need a good substrate.
