I can't guess really
I think this time around, it's important to choose someone to emulate (closely) & not get distracted into taking a bit from here, & a bit form there ...
Eg, if you start with ADA soil etc, then use ADA methods to establish the tank - which includes lean dosing rather than EI type fertilization
Tropica is fairly similar - like ADA they have a method they've put into their 90Day App
Anywhere you look, George Farmer, Jurijs mit JS, ADA, Tropica, Green Aqua, AquaFlora (Filipe Oliveira - hope you manage to get to his workshop today or July 1 (Destination Aquatics)) etc - all plant very heavily from the start
If you're short on plant supply funds, then do a combination dry start, wabi balls etc so as to have lots of healthy plant mass upon flooding
Then run high CO2 for the first weeks until plants have decent amount of thriving submerse growth
If there's much ambient light, run CO2 24/7 - lower levels CO2 during non-photoperiod, then increase as usual for photoperiod
As an example of plant growth despite dim lighting - hence benefit of CO2 non-photoperiod -
I moved some Rotala H'Ra to my under the stairs alcove tank - it's been barely growing, sparse tiny green leaves despite decent CO2 & fertilizers & light
Tank is only dimly lit until LEDs come on BUT the R H'Ra is always "closed" & would barely open despite running lights 100% from 6pm - midnight
I finally took notice that despite the very limited light, the H'Ra was "open" before noon & usually "closing" by 5pm - this didn't reverse just because I turned on the lights
This past week I've finally switched tank over to noon - 8pm photoperiod & the H'Ra is finally beginning to look like ... well ... H'Ra (with ~3cm new growth)
