GHP PH Up & Down Cause Nute Burn?

Hey all,

I'm on the last two weeks of a 8 week flower in my hydro system. I'm following the Al B. Fuct plan and trying to replicate his techniques.

I just changed my rez and nutes, but messed up & added too big of a splash of JHP PH Down to correct it. Then I had to add some GHP Up to balance out for my oversplash to get the desired 5.8 PH. I had already added all my nutes, and everything was perfect spot on at 1500 before adding the PH Up and Down solutions. Now the PPM has jumped up to 1700! Will the PH UP & Down solutions from JHP cause nute burn if it brings the PPM up above where it should be? The plants are already telling me that they are maxed out on nutes as it is.

My tap water is 500 PPM. I let it sit for a few days to let the chlorine out.
I add CANNA two part nutes in equal amounts to get 1000 PPM.
Combined Nutes and tap [mineral] PPM. 500 Tap + 1000 CANNA = 1500 total PPM.

I'm thinking that I should try to get it back down to 1500. I could give the dumped nute/water solution to a friend who's growing out doors some massive Sativa trees haha. I just hate to waste it. And hauling water is such a pain in the ass, and a security issue.

The think the only time I see an increase in PPM is after I've corrected for PH. PH creeps slowly up. I'm using 35% H202, so it is a very slow creep not associated with pests.

pH up and pH down are nutrients.

Potassium hydroxide is very high in potassium, phosphoric acid provides phosphates, and nitric acid provides nitrates. NPK.

Yes. They add nutes to your res.

For the chlorine I add a dechlorinator slightly less than what the manufacture suggests, and let the air stones knock out the rest.
If you don't want to buy the dechlorinator just add airstones to your holding container. Should only take a few hours VS a day.

Thanks. I wasn't thinking that they would add anything that could cause nute burn is all. Like the 500 ppm that comes out of my faucet. All dissolved minerals. I just add the 500 to the 1000 recommended by CANNA for a total of 1500 ppm.

Not a problem with chlorine. I let new water sit in open container for a few days before change over.

I usually add 10% nitric acid to my tap (also around 500ppm), which causes the carbonate to leave the solution as CO2, leaving calcium nitrate.

Man that might just be way too much nutrients. I have a lot of D/O in my water so my PPM can be lower but still my PPM are at 420 and I'm gearing towards the end of flower. That is an EC of .6 ... These are those plants btw White Widow auto x 3
