FYI I checked out the website Korn suggested and found a straight forward article on using distilled white vinegar, https://mattgadient.com/my-attempts-at-adjusting-ph-for-plants-with-vinegar-and-citric-acid/. So I did some testing with my water jug and found that when I put 1 tablespoon of distilled white vinegar in the 2 gal watering jug, mix it thoroughly I get a measured PH in the upper high 5 range. So, I am watering Mon, Wed & Fri, 1/2 gal each, with that and Fox Farms trio also added at the same time per their directions. On Sundays I flush each plant with 1 gal of PH'd water only to keep the nutrients from building up to much. I have attached some pictures of the results which clearly shows improvement (#1 is the plant in my original post and #3 & 4 are the same plants posted by me on 7-16-20, 6:27 PM. All are beginning to flower now and I think it's time to thin out the fan leaves etc... So, Thanks again to Korn for his suggested website and everyone else for all their helpful feedback and keeping me pointed in the right direction. Stay healthy and safe...
I too google searched for lowering ph. As was mentioned earlier lemon juice or vinegar came up, I had no lemon juice but did have white vinegar so this morning checked my water (8.4) added 1T to a gallon and it came out 6.3
