Accidental cbd-a conversion (unknown?)

If Cbd isolate contains high amount of cbd-a , will ceeping temperature low also convert the A ?
Lets assume i know how to perform conversion.

And how would 50/50 thc/thca behave
40/60 …?? 30/70??

Would it chrystalize?
Are there any visual clues to identify cbd-a and/or thc-a, off course when there is big diamond its easy but those take time to grow, how does it look when it starts to chrystalize?

You’re not going to have cbda in an isolate/distillate product

Thats really helpfull , saved my day.

Lets say i do have some cbd-a in my cbd, lets pretend.
