General Hydroponics

Hello all, I have a quick question concerning the PPM of my nutes. I am using General Hydrponics Flora Grow, Flora Micro, and Flora Bloom. I check my water for PH and PPM before I mix my nutes and my PPM never even shows on my EC meter. After I mix my nutes according to the chart my PPM should be around 500, but it always climbs up to around 1600. How can I mix by the chart and achieve the PPM that is recommended on the GH feeding chart? Thanks for any response.

less nutes or more water

I've been adding water to get the PPM ratio that the feed schedule recommends, but why would it be listed as that when you cannot achieve it with the amounts on the schedule? Thanks
