Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)

Hongostarted grow question a year ago

Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?

First, do not overpay for an acid or base to use in this way... It should be cheap... and as long as it doesn't cause a precipitate or otherwise fuck with nutrients, it's going to wrok as well as any other acid/base. People who think the acid you use impacts how much pH can swing or whether it is a temporary change are confused about reality... The reality is, any unbuffered nutrient products will liekly have pH swings -- this is a sign of a shit-ass manufacturer that doens't really know what they are doing, if it occurs.. it is not the fault of the particular acid used. Anything unbuffered will be a risk to swing in pH for absolutely silly reasons that are easily avoidable. If you experience wild pH swings, buy better fertilizer, imho. fwiw, this particular context does not seem to meet that threshold.. this seems like an easy fix. 3 gallon jug of white distilled vinegar is hard to beat, and more uses around house, too. Get some 3mL pipettes for easy measuring. you might need 1-3mL per gallon. (maybe larger pippette or measuring cup, if you deal in larger volumes) Maybe a little extra runoff will speed up the process of shifting the pH, but you don't want to leech your soil of nutrients too much, either... If no major issue, i'd just give enough for a little extra runoff compared to normal and let it glide down to the new pH you target. You don't want sudden, drastic shifts in pH, anyway... Further dialing in ratio and concentration of nutes will probably have a more beneficial impact than the pH. pH is important too, but shifting it a bit wont result in an easily discernable improvement to growth with just your eyes. More light, better ratio/concetration would be teh biggest pieces of the pie - light being 5x more important and nute-related stuff is more about not stepping on our own feet. the spots you see might be from the pH and it might be from ratio/concentration resulting from soil+fertilizer... it'd be folly to assume one and ignore the other possibility.

If you want to lower the pH of the soil to around 6.4 i would do a flush. Flush with water that has a pH of 6.4. Flush slow and steady with the amount of water it takes to get the desired pH. Before the next feeding do a top dress and water at a pH of 6.4. .

If you're running organic ammendments PH usually isn't a issue if you are a tea would healthy up the microbial developed and then they would balance things out if your running other nutirents that aren't organic A flush would do at 3x the pot size with the PH you're looking for There isn't much to go off here for pics, and you don't have anything posted as to what nutrients you're feeding them along with that it looks like a Boron deficiency 1/4 to 1/5 tbsp of Boric Acid per 4L of water. This will be absorbed very quickly however if applied too much the plant will burn very quickly. But with the limitation on information it also looks similar to Phosphorus deficiency which you can remedy by First, balance pH (Hydro: 5.8, Soil 6.0 - 6.9) or re-apply nutrient mix if necessary. Organic Solutions: • Bat Guano • Bone Meal • Crab Shell • Crab Meal Inorganic Solutions: • PK Boost Supplements • Phosphoric Acid (Soluble Phosphorus however raises pH quite a bit)

PH- organic, as that's the way you leaning right. Ph - from biobizz has worked with every brand of nutrients I've used thus far. Very potent. . So. As your soil is high to equal it out I suggest u try give maybe 5-5.5 and see does she start soaking up the soil again quickly. As that'll be how you know with dry additives as your PH should come from your water source. Good luck.
