Any addition of nutes is gonna raise some level somewhere. How much room do you have to grow in. 8-12 oz per plant? You want close to an lb.?

Fertigation is a system that applies soluble fertilizer to plants through irrigation water. It's common in greenhouse, hydroponic and irrigated high-value crop and ornamental production. Adding fertilizer to irrigation water increase EC since fertilizers are salts.

To use EC to check fertilizer levels, first check the EC reading of your water. Then take an EC reading of precise mixture of your fertilizer and irrigation water in the desired concentration. To check the amount of fertilizer that was added, subtract the reading for your water from the fertilizer that was added.

Now, check your fertigation water at any point along the system. Its EC should match the readings for the mixture. If it doesn't, check injectors, valves and nozzles for blockage or other problems.
