Yeah, I know the pH is a bit high - I didn't want to pH adjust the nutrient solution in my rez though - heard that's a 'no-no'. Instead, i'll be adding some pH'd RO water to top off the rez in the next few days - that will bring down the overall pH a bit as well as the ppms which are already a tad higher than they probably should be at this point.
OK, once again, I know nothing.......I read this........" I didn't want to pH adjust the nutrient solution in my rez though - heard that's a 'no-no'".................... And I wanna know...................
Where did you hear/read this?
I may be committing a cardinal or bluebird sin here, but this is what I do.
FYI: 1st of all, I have found that for some ungodly reason, when I take PH samples from my site level/drain tube, even if I fill a cup, drain it, fill it again, then pour half off (it's my ritual) and take a PH reading from that sample, it is invariably a 10th of a point or more higher than if measured at the res itself. Weird.......
I can go back and forth from the sample to the res and repeat my findings. I do check calibration of my PH meter on a weekly basis. It's pretty much rock solid.
But back to my process....
So, I have an extra bucket to sit my top bucket/plant into when I clean & change out the bottom res. My plant stays in my tent under the light while I go about my business (this only works for awhile, then becomes unwieldy, especially when under Scrog)
I prefer to mix & balance in my res as I know I have it dialed in as one unit, not two or three (gal) units. (I run DYI Water Farms, 5 gal buckets, constructed with GH WF Plumbing kits & 10" Net Pot Caps) I have never been able to drain the last 1/4 to 1/2" out of the bottom bucket via the drain tube, and I always find some hydroton sediment when I dump a bucket (water my outside garden)
Best case nute prep for me, is to mix & balance the night prior, in spare bucket, & re-balance PH (if needed) the day of change.
I do not always pull off the "best case" change outs.....and when you are making PH changes and Nute changes at the same time, it's a whole lot easier to do it in one container, not in an add back process.
Once your plant is in the screen (if you intend to scrog), you can forget about the bucket swap.........everything is add back until you change the res out. The good side of this, is by that time, you have dialed your nutes in, and do not experience large PH swings, unless your into self-destruct.
Don't laugh, known to happen..............frequently.
So after all this rigmarole that I put myself through....................Your saying I might be doing the wrong thing?
Geesus..........................
It's a wonder my plants survive............................
