Nutrient help how to mix for soil

do I add one at a time, or do I mix,all in. one container? help please.

on your Base Nutrient bottles,most likely an A+B

it should say how much to add per gallon of water,add less then what it says and move your PPMs up slowly each time.

I'm using david's grow that came in a kit 6 bottles so just. mix bit like it it say and I will be fine?

what soil or medium are you using and how long have they been in the medium?

do you see any signs of yellowing,leaves turning light green?any burnt looking tips?
