Water runoff from soil low Ph

So when I am testing the runoff water from my soil I am getting real low PH....I am phing the water when it goes in....Does this mean my rootball is in a unhealthy state if so how can I correct this? I imagine flushing but what I would like to know how to stop it from happening at all.....Should I be phing the water much higher that I water with? Does it even matter what the runoff ph is? ty

What are you using for soil?

Top dress with some dolomite lime and water it and carry on. Your fine.

How old is the plant? It's common to get salt buildup in early- to mid-flower. In that case you'd want to flush with mild nutes. What are the ppms of your runoff?

Usually when this problem starts to occur is mid flower I usually combat this by doing a tiny bit of flushing...well i just water it with plain water then go back to mild nutes. I dont know the ppm.....I dont have ppm or ec tester Im not at that level yet or cant afford it basically lol.

It sounds like salt build up. Feed less strong. And/or, mix enough that you get 20-30% runoff each watering. If/when it still happens, flush to get about 100% runoff. For example, if you're in a 2.5-3gal container, mix 1.5 gal of weak nutrients (1/4 to 1/2 strength) and pour all that into the soil. Go slow if you can, let it soak, then pour more. I try to give it 30 minutes to pour all that through.

Adding 1-2 Tbsp/gal of dolomite to your soil before planting may help. But, it's not going to fix overfeeding.

I have this ppm meter for $15. When the runoff ppms get up to 1250, I know I'm heading toward a problem. 1150 is ok for me. I don't measure it much now. But, when I was struggling with salt buildup, it was very helpful to see the trend. (Now I feed half what I used to, I try to water for 20% runoff. Or, I accept that I'll have to do a larger-volume runoff in early to mid flower. I might check the runoff ppm in flower.).

Every synthetic soil grower needs ppm meter.
