Good day
I have been playing around with different ei fert calculators. The one I have always been using seems a bit off. On the current one I have always been using I get the following results pic attached. If adding 15gm of kn03 im apparently getting 37ppm nitrates. But on rotalabutterfly.com/nutrient-calculator.php when working out dose to reach target and I add 35ppm it says I must add 71.34grams of Kno3 to 500ml container and then dose 100ml. So please advise which calculator I can use. Looks like my one might be wrong. My plants have been growing nicely with current stats.
Please assist.
Thanks
