is calcium chloride a good thing to use to bring down humidity in flower or veg.
or does humidity have to be high in veg and lower in flower
what are the advantages and disadvantages of really low humidity in flower??

In veg 60-70% is ideal. In flower 40-60%.

With RH above 70% the pressure outside the leaf is too high and inside the leaf is too low. This causes the stomata to close. Then they can't transpire.

Another thing with too high RH in flower is increased chances for mold and other issues. Lower RH in flower also promotes resin production for its own protection and our enjoyment.

I don't know anything about calcium chloride for RH control.

Hope this helps in some way.

The point of this is balance; you don't give your plants a thousand watts per square foot of light on the theory that more is always better, do you?

Stay within the suggested range for optimal benefits. Trying to hit one exact number and keep it there is an expensive and counterproductive fool's errand. Running excessively low RH in bloom reduces yield and increases the chances of nutrient burn.

Well said my friend.

Don't nitpick, you will never create a "perfect environment". I haven't.
Until you get EVERYTHING perfect and your growing skills are top-notch, and you have nothing else to worry about, just try your best to keep one plant green and healthy till chop. Then you can worry about tweaking your conditions to get a lil bit more of one thing or a lil less of another. Keep it as simple as you can for now. Do what you can and don't sweat the small things. We have all learned as we go. I sure didn't start out pulling 12-14oz every other week in perpetual. Sure didn't have a "just for me" tent with "just for ME" strains. But I do now! I got it with baby steps. Take your baby steps and roll with the punches. Two years from now, if you keep growing, and I know you will, you gonna look back and say "damn, I really used to sweat some shit that seems so small to me now".
