Organic nutrients and ec/ppm

Is there any point to check the ec/ppm of a nutrient solution with organic nutrients such as biobizz? I read that since organic nutrients dont have any actual minerals or dissolved solids it won't give you an accurate reading. Is this correct?

No incorrect.
EC is still a useful measurement in organics. I do think an EC meter is a useful tool to have for any garden.
For our purpose, it's essentially a measurement of plant available ions (nutrient salts) in a solution.

It will give you an accurate EC reading.
It doesn't measure what isn't yet plant available. A lot of organic compounds need to be broken down, dissolved, converted into a plant available form. Like the saying sometimes goes "less is more" or "a little goes a long way".

If the feed charts don't have a recommended EC value, then not really. Though that's not to say it isn't a useful tool to have.
There's no reason not to know what the EC of your mixed nutrient solution is. It's useful data to know and have.
Instances like mixing too strong by accident, you'll notice if you check the EC each time.

FWIW if Biobizz is fully soluble and you checked your mixed solution with an EC meter, you'll probably find the EC to be in a similar range to a hydroponic solution anyway.

P.S.
I even use an EC truncheon to mix up worm bin leachate to water. Works like a charm.
