Can I use tap water and adjust the pH?

[Green75]

I have four in five gallon fabric pots...I mix up a five gallon bucket of water and nutrients...ph to 6...I give each one
1 1/4 gallons...every four days...that's when the pot feels like it's an empty box weight wise...I let my coco blend medium dry out before I do again

I feed three times then strip/flush once then back to feed..

Ppm means.. part per million...when talking about nutrient strength ....some read it in.. ec...which is electrical conductivity of the nutrient amount in water...

Example...I'm at 1540 ppm.....also can be read 2.2 ec..

They look like they're doing very well to me! When it comes to the Flora trio, I've always had good luck following their nutrient schedule at half strength. I personally don't measure PPM when growing in coco (though many growers do). I'm not sure if you're interested, but this is the schedule I use for coco. It's just the regular schedule by General Hydroponics, except cut in half and converted to imperial measurements.

As far as what to do with plants that are different heights/ages, that can definitely be tough! It looks like you're already in the process of LST/bending which you can use to help bend over and secure the tallest stems. If you keep pulling the tallest stems down and towards empty spots, you'll eventually have a full canopy that's flat like a table, with all the colas about the same height as each other.

I can see plant twisty tie on your plants, so it looks like you're already on the right track!
