Salt readings and what they mean?

My tester checks PH, EC, TDS, and salt. My question is do I need to monitor salt levels and if yes what should the maximum allowable limits be. My one res is running 960 TDS, 1365 EC, 5.7 PH, and 675 salt. My bud res is running 1530 TDS, 2.1 EC, 6.4 PH, and 1.3 salt. Thanks for any help!

Not sure on what your asking here? And what tester are you useing? Guessing it's not a handheld. And unless your at the end of each. Veg and flower you are pritty high in your TDS PPM.

Also in hydro 6.4 ph is way to high. Should be 5.0-6.0.

2.1 EC is really high. I run 0.8-1.2 in Veg and 1.2-1.6 in flower

Thanks guys, sorry i hadn't flushed the res yet, did it while waiting for replies. I am now running about 1250 tds and EC is 1500ish, Ph is still high but i have been running around 6.2-6.3 in 12/12 for the whole grow as it seems to stay there as opposed to trying to keep it lower, no issues! And yes i am lowering my tds as it is sucking up more water than nutes. But what I was asking is do i need to pay attention to the salt readings as well or just ignore. My water is from well and may have a bit of salt to begin with at certain times due to run off! The plants are doing really well BTW except for an extrordinary amount of stretch!! About 200% growth since turn! I am a hydro knowledge peasant so be kind..... Lol.
