do all salts count toward ppm, nutes, ph down etc?

taco flavored kisses for my ben

Everything raises your PPM you putting your unwashed hands in your res will raise the PPM, remember Plants shit too they eat nutrients and shit in the reservoir that also changes your PPM

thanks, but i have no idea how that was related to the question i had asked....

You asked if all salts count toward PPM and I pretty much said " Everything counts toward PPM"
What do you actually mean?
Do you mean when you use PH down it changes your PPM ???

Subtract the ppm that is in the water to start. If you have 300 ppm with no nutes and you want 1200 ppm of nutes make your total 1500ppm. The first 300 don't count. Start off light on the nutes and move the number up, you plants will tell you when it to much and then back it up 20%

I'd personally count about 50% of the initial water ppm as that does contain dissolved minerals the plant uses

my actual question was do the salts from ph up/down add to the heat of the water (chance to cause nute burn).. i understand about everything added to water will effect its ppm. i just didn't know if i had to adjust the nute ppm lower due to the increased ppm caused by adding ph down. according to GH it shouldn't be an issue.

[FONT=&quot]The ph down doesn't add to the "heat" per say. It ads to the ppm but in the form of phosphorus which is not a "hot" element like nitrogen.[/FONT][FONT=&quot]
