I have a meter that I'm using to measure my nutrients but it reads in ppm. My question is will that give me the correct numbers compared to a tds meter. Last night it read 534 and my water that i use to fill my reservoir is 130.

Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.
Hydro meter question?

Ppm is a measurement of TDS in Parts Per Million, so if your reservoir reads 500 ppm then there are a total of 500 parts per million of dissolved solids.
Also, if your tap water reads 130ppm, you need to subtract that much from the nutrients you add. So if your target is 500ppm, you would only be adding 370ppm worth of solution.

Thanks your input has been very helpful
i ahve always just added that amount of nutes i want so if my water read 130 and i wanted 500 i would add till it read 630, and i have never had an issue with my plants
but like was said above, TDS is measured in either PPM or EC.

Yes its a website link for growing "the other tomato" but is a great tool depending on you brand of meter.
