Coco runoff high

Coco runoff was 7.1 so I flushed it a couple times with ph 5.8 nutrient solution (1/4 strength bloom w/ full calmag) same as I been feeding it this past week. Only brought it down to 6.8

Maybe I should have flushed it with just plain water but I didn't want to flush all the nutes out just replace them.

They are almost 3 weeks old and look healthy actually I was just worried about the runoff. Only fed them 1/8 strength bloom the first week and 1/2 calmag.

My water is only 60 ppm so I used full strength calmag at week 2 and also have dolomite lime premixed in the coco.

Do you think the lime and calmag is redundant and making it spike to 7.0? Although my water is not exactly high ppm at 60 so idk. I heard this happens to lots of people so wasn't sure if it's a problem.

First thing that hit me - why are you feeding bloom nutes @ three weeks old?
If they look healthy, I'd trust them - don't look for something to fix. I'm not a pro, by no means, but I've never checked my runoff. If your getting runoff, with your waterings, shouldn't need to flush.

If it is a small pot let it sit in a beaker with the solution in for a few minutes. This will give more time to dissolve shit from the coco.

Time to play some rock, paper scissors.

I use to run CNS-17, Bloom formula for soil and coco from start to finish with just a little hydroplex for the bloom booster.

Sorry should have been more specific it's the fox farm big bloom bottle. Idk why they put the word bloom on it it makes it confusing. The tiger bloom would be for flower.

What he said ^^

Worrying about runoff will drive you crazy. If it looks good then no need to worry.
That's what it seems like, I guess a steady steady ph of 5.8 with plenty of runoff will keep things stable enough not to worry about runoff ph. I just hope I don't see burning when I increase the strength.

What nutrients are you running and what's your ec?
In my experience no need to check run-off in coir as every time you feed to run-off your resetting the medium.
Interesting, I wonder why my runoff was 6.8 after flushing with 5.8 ph weak nutrient solution maybe it's the dolomite lime I mixed with the coco. Not sure about ec I only have ppm meter and my ppm that was going in was 250 I didn't check runoff ppm.

Do you think that's really needed, isn't the spike in ph for the runoff normal. I been hand feeding three times a day as you said to make it more like hydro and giving it weak 1/8 and 1/4 strength feedings. Mixed 1 tablespoon of Dolomite lime every gallon of coco because my tap ppm is only 60 I hope the lime isn't causing it to spike because I mixed it in a big batch of coco. The plants aren't burnt or anything it's strange that the runoff is like that.

No need for lime in coco. You've actually put a pH buffer in a medium that's already pH balanced in nature. If you were worried about cal, there are better products than lime for that.
