How rigidly should you follow EI?
I do understand the EI dosing method (mostly). I understand that you don't need to do much testing, and that tests are notoriously inacurate. However, I did a 50% wc on last Saturday, dosed my usual 1/2tsp NO3 etc, and the nitrates have read 7-9 25ppm, 7-10 25ppm, 7-11 20ppm, 7-12 20ppm, and today between 10-20 (couldn't quite tell exactly). I have not dosed any macros since 7-9.
In light of these readings, should I have been dosing NO3 every other day?
