8 pot wilma ph ppm Questions

hi there this is my 1st time with a wilma system , used to mud :D,i am using a

600w MH veg/600w hps flo
canna vega AB/cannazym/rhizotonic nutes
in pebbles

my questions are .
it says on the bottles to PH the bay then add nutes.i did this and got the ph to 5,8 but once i added nutes (25% at moment with ppm @ 800),left for few hours an then ph = 6,9.i adjusted back to 5,8..but on the bottle it says the nutes adjust ph ,is this right ,should i leave it once i initialy set it @5,8 ?

also what is the best ppm ,babies are very young at the mo so only giving 25% nutes an going easy on them till they get established.my ppm is 800
main thing is the ph problem (confusion).
thanx for any help info advice

Yes, most nutes adjust the ph. I suggest you make sure your meter is correctly adjusted, and once you feel confident that it is, leave the meter in the nutes for 5 minutes or so, and you'll be surprised how much it can SLOWLY change in that time.
As for your nutes, I suggest a lot less than 800ppm. I keep my 'mature' plants that are vegging at 600, and brand new clones that have just rooted at perhaps 200 until they are thriving and then bring them to 500-800.

Ditto on the 200 ppm for babies and 500-600 for veg. I have problems with anything over 600 ppm personaly and run around 500

keep checking the Ph also make sure the nuits are well mixed
and I would readjust the Ph

first new battery and recalibrate meter

Daddy

the meter is new and workin fine.i will lower the ppm and just keep adjustin the PH.with reading info on the bottle i assumed i would only have to ph once lol thanx for the info ..
what ppm do ya go upto during flo ?
it also says to put nutes into res an leave for a while , how does that wrk with pumps on 15 on 15 off, turn pumps off for short while to let nutes settle ?

thanx for the help
