So I've looked around and cant seem to find answers to my questions. I have the ff trio and 3 week old plants in e&f I understand I use big bloom and grow big at the same time for veg? then us grow big and tiger bloom for flower? Do I add my nutes then test ph or adjust ph first? I cant seem to find a thread that explains how to test the strength of nutes with my ppm tester and what ranger am I looking for at this point? I've read all over to only us about half the strength at first as the chart on the bottle says? At this point do I following the chart for seedlings 1tb per gallon for big bloom and 1/2 tsp per gallon for grow big? Thanks in advance.
