Help me get my ph down 🙏🏾

Also, "7.3" isn't the end of the world. You'll eventually get it back down, and the impact won't be significant. it's one pot.. if throwing out a few dollars isn't a big deal can always just start new. or, start new and let that one soak in some acidic water for a while and use in future after you correct the pH.

pH balance after everything has been dissolved into whatever waer you add to the pot in future. You don't need much silica. If part of normal fertigation, i think it's only 10-30 ppm before it's just a hinderance more than a benefit -- reference material for google search. So an amendment to the medium needs to provide roughly that over time... this is difficult to guage. pretty hard to see effects of silica without a clone 'control' plant to compare - even so probably can't discern from normal genetic diversity and changing local variables etc... way too many moving parts. Since you are using coco coir, i'd stick to normal soilless methods. The advantage of soilless is tightly controlling exact concentration and ratios of nutes around the roots. An amendment with unknwonw release of silica kinda contradicts the method. You can figure it out, if you prefer this path with azomite, but it'll take some trial and error as far as adding too much or too little azomite etc. looks like it is fairly soluble but not very soluble, whatever that means, lol (water solubility 5.9)... could probably grind it and dissolve it to make a stock solution of concentrated liquid, that you can add a mL at a time to fertilizer. In your case i guess it's just the pH, but taht's still a huge hassle.. it's going to continue to dissolve and raise your pH over time until it is exhausted. Another reason to prefer adding it to your fertilizer, then as typical, ph-balance after all nutes have been added and dissolved. Acetic acid is a great option. Cheap and it doesn't add anything that can throw off your nutrient balance. Don't overpay for marijuana branded pH balancers (up or down) - they are just run-of-the-mill acids and bases. You can find the same ingredient for 1/10th the price. 3 gallons of white distilled vinegar (acetic acid) will last a long time. If your fertilizer formula is the same each time, it'll take the same mL per liter (or gallon) to correct teh pH.. measure it out 1mL at a time until you get there, then after that you ddn't have to go through that process again unless you drastically change how much silica is added or a similar effect.

Use quality soil / medium / coco / pebbles whatever. Why does someone buy shitty stuff that I have to set up from the beginning... So if you want to transplant, just use good medium.

PS: Next time add Azomite after pH is dialed in, not before.

Hey growmie azomite raises pH, that’s what’s holding it up. It’s alkaline and not easy to flush out once mixed. Keep flushing with pH 5.5–5.8 water, but don’t expect fast results. You could also mix in something mildly acidic like peat or add a little humic acid to help buffer it. Good luck with the rest of your grow bro 🤞 🍀 ❤️
