Does anyone know what the TDS is for a 1 week old seedling ?

I have 3 1 week old blue mystic plants and ive been looking around and im trying to figure out what is the TDS is for them? The PH is right at 6.5 and im using RO water no nutes but the ppm is 704 im just thinking thats a little two high? Ill have some pics up soon just wanted to get the right info thanks.

RO water with no nutes@700ppm? I don't think so. better check again.
either calibrate your ppm meter or get a new ro

ok thanks ya i thought something was off. What is the rang TDS for a week old?

if it is in soil, it is too early for nutes

ya no nutes i fix it needed to be calibrated haha thanks. The new reading is ppm is 370 and the run off is right at 400 and I'm using FFOF

ppm of my tap water is 363, RO should be lower? interesting

Well im using the ph up and down its in the crystal form. After i calibrated my ppm meater i checked the RO water befor it was at like 2 ppm but after i added the ph up and down it went up

filtered water at 6ph working great for me. if you keep putting ph

that makes sense, thank you

ph at 6.5 an your ph is going higher then it new to me every grow we put in ph of 6 an it never goes over 6.5 veg to flowering

Your welcome hog.

My ph is at 6.3 but my TDS goes up every time i use Ph Up and Down? so what im asking is how to i keep my TDS down while using the crystal form Ph up and down?
