I'm a beginner at growing weed and I was wondering if anyone Could help answer this question if I have to ph the water before adding nutes but my nutes affect the ph. Then do I have to add more ph down after adding the nutes? And what's the point of adding ph down before adding any nutes? am i supposed to add more ph u up or down? I have been struggling with this problem for about a month now. can anyone help answer my question? I have a brain injury so please excuse my grammar and spelling mistakes.
