    I am currently growing in organic soil, and with organic nutes, ph in a couple of my girls are out of whack around 7.0 7.1. If using vinegar to lower the ph how much would i use during the 2nd week of flowering. Growing in 2 to 3 gallon pots? and also do i use this method along with the nutes. or with water alone. Thanks oleschool

    Come on guys, can anyone out there shed some light on this topic. Just trying to find a good cheap ph up & down solution for organic soil using organic ferts. Thanks oleschool

    Get either General Hydroponics or Advanced Nutrients pH Down. Get it online or at a local hydroponics store. They won't carry it at like Home Depot or Lowes. A quart should run you around $13 - $15.

    What week you are on and the size of the containers isn't relevant. Whether you are using plain water or water with nutes then you need to check your PH right before you apply it to the plants. If it is too high, then add some vinegar to the water. Start with small doses until you get an idea how much it affects the PH. Lots of ferts will lower the PH so you may not have to add any vinegar on the days you are using nutes.
