Should water be ph'd when doing a flush?

If I'm doing a flush between nute changes or at the end of flwr, should I ph the water? I use RO water. Thank you!

bump. i wanna know too

You mean test the ph of the water?

You should know the PH of the water you're flushing with and adjust accordingly...

No, he means the pH adjusted to the level appropriate for MJ in either hydro or soil...

Actually, a good question...I hypothesize(as I'm guessing you do as well) that you do not need to adjust your pH, because who cares about nute lockoutat the end of flower) if all you're trying to do is get water in the plants system...Would love some more educated insight into this as well

Yes test and adjust. No nutes in flush. Then do the per schedule res change with nutes.

at the end of flower,no.before nute change,yes.

If you knew the answer whyd you post lol? OFC you test and adust, I've heard it makes no difference at the last flush of the flower; you can test it, but don't adjust it.

Thats sorta what I figured as well...

Also I'm not talking about a long flush between nute changes which I could see altering the whole plants chemistry. Just a flush for getting the old salts out of the medium and any additives that would effect the next feeding. I'm doing coco/perlite in smart pots, ebb/flow.
