first off thanks for the input. 2nd I do read read read and encourage everyone I run into to do the same. Lastly you would have to prove to me that by using the Lucas Formula I would not have ANY PH issuses. I'm sorry but I dont believe that just the mix you use can keep you from having PH issues, there are just way to many variables to make a claim like that. Of course this is just my opinon and I never claimed to know everything.
