OK so as i understand it ec meter measures how hard/soft you water is, tds measures nutes in water and ph measures ph obviously, but which are absolutely needed? im doing my first grow and want to try to save some money. ill be using fox farm 3 part nutes, Can I just use ph paper to test water before i water plants (with nutes in water) and adjust it and then test runoff for soil ph?
And just buy a tds meter later if i have plant problems and forget about an ec meter?
