I've been reading the forum and books but i am still a bit confused. I am using general hydroponics nutrients. Do the soil and nutrient water need to be tested before i water the females? How often do or should i test it and what kind of testers would you recommend? My friend just told me how much water and nutrient to mix up but i want to learn all the details so i won't have any problems and maybe get more weight with what i got. I'm currently using general hydroponics flora micro, flora grow, and flora bloom and during the vegetative stage i am using diamond nectar also. Would or do i need to use ph up and down? If so how do i mix those up?
