Does it rain where you live??
is RO water top of the line supply without ph?

Because rainwater is the best water you can use.. Its not hard at all, typically needs little pH adjustment depending on your feed, and brings some micros to the party too.. My rainwater is typically pH5.7 and ~17ppm.. When soil has been properly limed it works out perfectly.. Oh, and its free, just set up a collector under your spout, and keep the sun from pummeling it as best you can to keep algae and whatnot from coming around..

is it safe to keep in gallon jugs from the buckets for storage ina cool spot. and stay fresh?

Oh yea, No problems.. Its pretty clean to begin with, so the quicker you get it contained, the less will end up in there that can grow into grossness.. But most of the stuff I stored as backup just got dumped because I never found myself lacking fresh stuff..

Its not going to be buffered there at all though and will be easy to shift because its so clean..

it had been sitting 2 hours in buffer solution before test according to instructions.i dont use nutes every watering ,every other or third .i'll definately chek it wen nutes are applied..but if i can get a 5.5 to 6.75 during late flowering still considered pretty good from wat i understand.

Buffer solution is called that because its well 'buffered' at its calibration pH so even if it gets slightly contaminated it will keep an accurate calibration reading.. Ideally we want our water to be well buffered too lime and phospjoric acid and some nutrient salt reactions buffer very well in the 6-7pH range.. Other nutrient reaction products want to buffer too high, or too low, and that is why some ppl can never seem to correct their pH..
To summarize it will take alot more pH down to drop the pH from 7.0 to 6.5 if the solution is well buffered in that pH range than it would if the solution was nearly pure H2O.. This is a good thing because it increases the stability.. If your soil is well buffered, the pH of the water doesn't matter that much because the buffers will correct the pH of the new water (assuming its not buffered strongly at its current pH) instead of the new pure-ish water messing up the pH of the grow.. There are limits though..

i understand ,i checked it twice today and got the same reading.i'm well pleased.i jus want to keep checking everytime i water ..my plants thrive on pure water and mild nutes and ocean forest and get large and heavy tops ,avg 30to 35 plants every 75 days,in some cases i get one dry oz per gallon container.most of the time 1.5 oz 2 gallon container using sugar daddy at 7 tsp. per gallon every watering in the las 2 weex .1 quarter tsp. ching chang per gallon of water.thanx bro for all the help.
