Do you plan to run the strips and the "colored" cree strings together on the same 24v driver(HLG-600)?
If so, make sure that the "colored strings" have exactly the same vf / resistance as the F-strips, otherwise you get uneven illumination with the risk of thermal runaways. Maybe you need additional resistors to even out the difference.
You could work around this problem by switching to parallel strings out of 1 F-strip with 5x deepred + 1x far-red in series and using an HLG-600H-36A instead. All parallel strings would have the same vf and you will save tedious tests and calculations.
The same works with an F strip plus a 30v COB (eg.Vero18b) in series and a HLG-600H-54A.
PWM dimming in growlights can be realized by so called aquarium or reef controllers. There are several out there, stevesleds sell the HurricaneX controller, rapidleds sell the Bluefish and the Storm/StrormX controller.
They are based on Arduino or Rasp.Pi boards but you need a small 5v pwm to 0-10v extension card to control Meanwell HLG series drivers because they need 10v pwm or 0-10v for dimming.
You could even do your own, but it's a PITA to find all the code you need. Everything is fragmented in many forums and much is already outdated.
You can get a controller+extension card for ~$100, the better ones, like the Bluefish(10v pwm already integrated) cost around 200.

Pacificlightconcepts has also a zigbee compatible 10v pwm controller+hub for ~29+35$. Zigbee compatible means it can be also controled by alexa, philips hue or so. Also app control should be possible but I don't know much about this Amelech controller and which app they need. But 64$ is a really low price and you can easily control multiple controllers through the same hub and these hub has it's own UI to set up the lights.
