I've read the whole thread. I have a question on my behalf please. My pH tap is 8.1 -8.2 it is city water. When I check it with a TDS meter it reads only 30. My issue is all the PH down it will need and the salt build up. I switched from GH to AN. My god what a difference. 2 drops VS a 1/8 tsp. Just a tip to anyone using GH PH down make the switch you will be very happy....

What supplements do you think I should add to the water other then PH down? Should I be really concerned with this or just keep on keeping on? I'm growing in soil what do you think is a good PH to run 6.3?

Thanks for any help Great Thread:thumbsup:
