New grower advise

You said you run 24hour light schedule with auto flowers does it effect them if I switched from 20/4 to 24hrs? Or should I just stick with what I started ?

This early no. It is my belief that your light is better staying on then getting a hard restart every 20 hrs.
Plants behave a little different on 24hr but once dialed in its gold.

Anything I should watch for when running 24hour light?

24/7 light schedule was always my favorite when using mass built led lights. Since switching to Autocobs and with the addition of Quantum boards, I changed to 20/4. I might try one plant next run 24/7. Probably the Quantum board.

Use VPD charts to dial in your humidity/temperature. The nice thing about 24/0 is that temps and humidity can be dialed in and they stay reasonably constant.

I tried changing to 20/4 on my current grow in order to deal with a leaf color issue, but the temps went too low and humidity too high during lights out, so I went back to 24/0 with dialed VPD. In order to make 20/4 work, I would have had to add thermostatically controlled heat in my 2x4 space which is doable but a pain in the butt, and physically difficult to stuff into my small space. So, 24/0 it is for the rest of my grow.

Hey thanks for the info! I did not add anything to the Promix. Waiting in my ph pen to come in the mail but I have been using 3ml/L of cal mag each watering and .5ml/L of GH - flora nova grow.

I don't add extra ca/mg until toward the end of the stretch.
