Hello and welcome to the forum.
What nutrients are you using. Please include N.P.K numbers.
Cross check your E.C meter with a ppm meter.
To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1 * 1000/2= 500 ppm.

When mixing nutes (botanicare) for soil I just follow what the bottle says.
I did dip my pen in the last few gallons I mixed for Dirt and it was 1.5ec.
Now what I mix for dwc on bare roots I would be 1/3 less. 1ec for example , then I would monitor and adjust according to there needs.

Enjoy and good luck with your grow.

I normally don’t worry about EC but now I want to be dialed in and I’m realizing maybe I’ve been shorting myself.

I personally just follow the recommended bottle feeding but cut dosages in half.... I don't ph check and stopped caring about ec/ppm... that has not stopped me from getting half lb harvests per plant!

You can Measure the EC of your reservoir or do a pour through if in soil and compare the EC & pH to what you were originally feeding. This will give you some indication on what the plant is or is not using.
