What is the highest temps they saw - ambient air temp , and nute souloution temps ? PH Hi / Lo also ?

Last time I waterd here I used tapwater and just sucanat because I've been flushing for a while . I checked PH before and after the sucanat was added and saw no chg. in PH ?

I have seen the slight white foam on top in my res. too , but w/ my system - once a day I shut valves n let all my nute soloution collect in the big res. and use a 18volt dewalt drill on high w/ a 5 gal. buck paint mixer to mix soloution up before chkin or adj. PH . My doing this mighta kept mine from going stag ?

Was there any foul smells ?
