Can I add garden limestone like a top soil mid flower to help regulate pH levels?

Had bought garden limestone for my next grow and am beginning to wonder if I have a soil pH issue. I've already determined i have nitrogen and phosphorus deficiency . Despite correcting the nutrient issue by adding the correct npk . Not seeing any great improvement .

pH has been 5.8-6.3 throughout the grow and rechecked before feed . I'm wondering if the pH in the soil rises and would adding limestone like a topsoil would it help balance the salts when feeding ?

have you checked the ph of the soil? not the runoff or any other stuff the actual ph of the soil? in anycase limestone is used for raising the ph of the soil so if you suspect high ph don’t add limestone

Does it not buffer hitting a maximum of 7

Maybe it’s a lockout

If you have any decent bagged soil there is no need to be fussing with pH.

I'm using bio bizz . Maybe use limestone for coco?

Checked it is sitting at 6.8

Bio bizz recommends 6.2-6.5 PH. Just invest in their PH up and down you can buy it where you got your other bottles.

That means you have a high PH. If anything you will want to bring the PH down. Limestone is alkaline meaning it will raise your PH near 7 or higher.

When it comes to pH fluctuations what is the best way to manage it with soil. What I'm trying to say is. When you balance the pH of your nutrient solution the following day that pH level will have risen .

If I'm feeding every 3 -4days I assume the pH level in the soil rises until it drys out leaving behind salts .

Usually I water first to try and flush the soil slightly before feeding with nutrients .

Any nutrient solution I have added has been around 6 I've never gone above 6.5 and usually bring it down as low as I can get or somewhere in the middle so 6-6.2

Good question, the best way to manage ph in soil is going to be by using microbes and not using adjusters unless absolutely needed. I would try feeding everything and don't stress PH unless you see problems. I get you will want to see the most out of your nutrients but in organics PH is less extremely serious than with Hydroponics.

with Reverse Osmosis Water I run CYCO Platinum Nutrients Base Grow/Bloom, Potash & Swell and don't mess with my ph at all in coco. It always is 5.7-6.0 without messing with it. Plants do great until I start trying to correct stuff with acids and alkaline solutions PH+-. Using well water or city water may vary your results there..

One product that I used when I used to grow in the Michigan Made Mix (m3) super soil was Recharge by Real Growers every 7-10 days plain by itself and water in completely. It's packed with beneficial bacteria, kelp, molasses, minerals and other goodies I'm probably missing. I still use it to this day even in coco with synthetic fertilizer to add some microbial life to the coco.
