hey Blue ,
i'm using gen. hydro flora . their recipe 321 / 123 . mixing micro. 1st - grow 2nd - bloom 3rd . then adding 1 tsp. of cal-mag per gallon . we have pretty decednt water here only 70-80 ppm . so i haven't been to worried about r/o water etc.

ph hasn't flux. since we got it all recirculating . just the usual ph rise in the first 12-24 hrs . then re-adjust once n were good .

i been using flora kleen now n then too .
last grow was a leaning exp. whenever they got ugly i'd flush the hell outa em w/ F/K -n- start low w/ ppm n wrk my way back up till i find their happy spot . kinda like you had just described .

didn't have a good p/h pen last go round either , fishtank 2 drops deal was a pita so p/h wasn't watched as closely as this time . got a good milwakee for 22.00 on ebay .

i found g/h flora series in 6 gal. jugs for real cheap too w/ free shipping .lol like 210lbs . they sure screwed themselves on that one . hydro empire .com :dance:

i don't like all the wet -n- ph horror stories w/ R/W as a medium , i even pre-soak my starter cubes overnight in p/h adj. water due to stories i've read on here . i found a local source for hydroton for cheap -n- got 5 -50lb. bags for 100.00 .

wish my balls were big enuf to post some pics. but they're not . lol
peace
your cuz
crispi :thumbsup:
