Fert question

This is my 1st planted tank, I've done tanks in the past with a couple plants (cichlid, turtle etc) but I have recently fallen for the allure and challenge of a heavily planted tank. So here is the setup:

75 gallon
4x54w T5 12 on 12 off
pressurized co2 (2 bps)
eco complete 2-3 inches or so over sand
plants: s. repens carpet, micro sword carpet
red ruben, red tiger lotus, giant amazon mother, red flame amazon
some anubias on drift wood, a tiny bit of java fern on some lace rock
2 bronze crypts, red ludwigia glandulosa and some jungle val.

eheim 2217
great water flow, surface agitation with powerheads

community fish (neons,congos,ottos,pearl gourami, siamese algae eaters, nerite snails and others. mts. shrimp)

Now for my question: With this setup Im planning on just fertilizing with DIY osmocote root tabs about 6 inches apart (going to start slow with just 6 or so total and add more gradually, then stop when they are 6 inches apart) and for micros dose with flourish (same strategy, start slow then increase up to recommended dose)

In your opinions will this regimen be enough? of course I will adjust strategy based on results. Any other input is welcome!

Too much light for too long + slow release Osmocote would be my concern.(plant's won't wait for slow release Osmocote at this light level).
Plant's do not know how many other plant's are present in the tank or what size tank they are in.
They only know/feel how much light energy is beaming down on them, and higher level's of light will require higher level's of nutrient's for the plant's to use as fuel for growth.
They will need the food sooner rather than later.(they have no choice)
Same goes for CO2.
I would want to be able to raise the light up off the tank, and dose water column as well with macros/micros to help compensate for slow release Osmocote.

Its a dirt cheap one I bought on Amazon. I cant remember the brand. Its cheaply made honestly but it works great for now.

Thanks! So maybe some water column dosing with some dry ferts? Im not looking to spend a ton of money on commercial liquid stuff. Any recommendations?

That would be one in the U.S. for comparison.
But also by comparison, and not experience, most high tech tanks seem to have algae
problems if four bulbs are used unless the owners are experienced at using the injected
CO2 and the hrs of light are kept under 10 per day.
You may have an Odyssea fixture. I have one on one of my tanks.
They are made cheap, but have excellent reflectors that produce high PAR levels.
My two bulb Odyssea will work/w one bulb. If your fixture will I'd suggest you use only
two till you have lots of plants in there growing well.
