New Grower Soil pH Help

[PoopsMcDoogle]

I checked my scribblings and it's been over two weeks since I mixed my soils. I did slurry today and soil is up to 6.5 from 6.2. So I guess it's good to go. I figured out what was wrong with my problem plant also I think. I limed her soil to 6.5 to start with but didn't give it any time to do it's buffering. I never really realized how important soil preparation is. Keep that in mind noobies like me. I did a slurry on her soil today as well and her pH was 7.0. I also have two other girls at 3 weeks in same soil with I'm guessing same pH going on. What should I do?? Flush next time to water and put back nutes at quarter strength at 6.5pH? Does the lime flush easily?

I am thinking that the lime doesn't really flush out. It takes time to raise and now you're too high is the problem? Gotcha. Now you know to give that mix a while to stabalize, sound like you're good though on new soil mix.

For the others at 7, that isn't awful. If you feed with nutes around 6.3 the nutes will buffer it down some and it's actually kinda good for it to start at lower 6s and work it's way back up closer to 7 as it dries. That way it goes through the whole spectrum of ph intake and gets all it needs to absorb. Promix(except for my bag of course) buffers around 7. Nuted ph water lowers it and it raises back to the mix's ph as it dries. Hope this helps. If it raises more than 7 you may need to try a flush.

Well I now that I've been letting my slurries sit around the numbers have changed slightly. My problem plant is reading @ 6.7-6.8. I took two different slurries from her soil. One with a water to dirt ratio of 2:1, the other half:half and same reading for both. I'm guessing as she's drying the pH is buffering back down some too hopefully. I watered at 7 last time two times. Somebody told me to water at 7 and it would drift down. I don't remember who told me or even if they were a credible source. I'll do as you say. She probably isn't getting much of the lower pH spectrum as I have soil in high 6's and been watering at 7. I'm going to give a good flush next water. Fox Farms Ocean Forest has lots of salt build-up I hear. Mine have always responded good to flushings when using it.

Cool. That sounds good to me. And that just depends on what mix you have and the starting ph. I have been told to water feeds with a lower ph and let it slowly dry and raise back up to 7, which is what Promix normally is at on ph.
