I was actually going to try that today, they are looking better in my opinion so hopefully that was it. I will test it and send pics in laterCan you do a soil slurry test? I feel like that'll rule out PH or its a PH issue.
I forgot the recipe, quick google it. Pretty sure its 1 part soil (go under the surface) and 2 parts water? Mix very well.... let sit for 15 minutes and then take the PH of the slurry
edit: you need distilled water, I forgot
