E.C question

Hi there just a quick E.C question and i don't mean to be rude but unless you know the answer be quiet..

If the E.C of 10 litres of my tapwater is .64 and when i add my nutes the E.C is .88 then what is my E.C?

Is it .24 which is the difference between plain tapwater and tapwater with nutes added or is it .88 ??

i had a few nute probs last grow and i understand that to regulate my nutes properly i need to know the answer to this one thanks in advance for your help...

.88

.24 is representative of the NPK only. Plants can only handle so much EC, so the higher EC of your base water, the less NPK you can give at any one time.
