What have you been PH correcting your water to?

What have you been PH correcting your water to?

I have been using a ph pen to measure it. And ph up and ph down to bring it up or down

That’s good. What number are you PH correcting to? For soil you should be between 6.0-7.0. Your symptoms look similar to ph issues I’ve had in the past.

Good. Are you letting your tap water sit for 24 hours before using it, and do you know the PPM of your tap water?

Yes I met it sit out for 24hours and I do not know the ppm

Good on the first part, not so much on the second part. Not knowing your tap ppm may be causing your problems. If your tap ppm is high (over 200) and then you add nutes on top of that, will most definitely cause burn. You can get a decent TDS meter on Amazon for $20-30. Or you can take a sample to your local hydro store and ask them to test it for you. But you really should have a meter.

So if your water is a high ppm how do you adjust it

If it’s high, or you just want very clean source water, you need a Reverse Osmosis (RO) filter. Or you can get bottled water from the grocery store. Either of those is going to be a bit more expensive than the TDS meter. I got my Hydrolodgic 150gph filter for under $200.

Check your ph on your run off water . I bet your plants ph is off .

Checking the pH of the runoff will have him chasing ghosts. Runoff pH is not a good indicator of the pH in the rhizosphere. A slurry test would be more accurate.

So just take some soil from the top of my pot and do slurry test or take some soil out of the middle
