Bear I cannot thank you enough for posting this but I'm afraid I do not for the life of me understand the conversion thing etc... Allow me to study this entire thing for awhile and I will return with questions; probably about nine million of them. I want to try this 3 part thing but also want to understand it before I do. Where exactly does the Cal Mag fit into this equation? You said it was a must for you; and what else do you add to this? Lk?

I just tried a version of PIF's solution to adjusting ph daily and it worked great for me--involves rotating the solution daily, pumping out the stuff in the individual buckets and returning it to the top rez allowing the fresh in already ph correct. Can this method be used in conjunction with this? Again thank you so much for posting this...I will study up so I can try it.

PS JW--I tried the above on PIF's theory and it really did the trick...no lifting the buckets out etc. I ended up throwing some of the solution away as I could see small bits of root and crud in and added put in some fresh....I DID NOT HAVE TO CLEAN MY DRIPPERS TODAY. I am in heaven!!! Thanks PIF.
