a friend who is setting up her first ever grow has gone and bought a tds meter, now i know nothing about them but know mine goes up and 1 start around 12 upto about 24 when flowering (i think its done on conductivity(?)), she has bought one that is ppm and wants to know how much food she should add. she can't afforsd a new meter yet and is too far from me to lend mine.
i can't find how many ppm she should be feeding her plants on is there a way of converting the conductivity into ppm?
