From what I understand the PPMs on that chart are what they want you to feed at, not run off. @Countryboyjvd1971 feeds per the chart on what I think is a FEED then WATER then WATER then FEED schedule. Feeding that high of PPMs scares me.
So I do FEED then FEED then WATER then FEED schedule. I go in with lower amount of nutes, so a lower PPM, but feed more often then @Countryboyjvd1971 does. Just not as much as he does at one time. In the end we probably feed about the same amount for the week. I just try to keep my run off PPM around 1100 to 1400 at all times. This is my first grow so Im still trying to figure this all out. But it seems to be working alright so far.
