Hey Mon'! I lost you for a moment, since Bud-E moved you here,.. and yes, the Infirmary has been a fekkin' zoo lately!
.... OK, let's see,... Mongol, that's a weird pH test kit! Why does the soil look so sandy? I know about slurry tests, but this one is not looking quite like what I'm used too,.. best as you can, please explain how this test is done,... that you're getting consistent 7.0 is no surprise, from the looks of the label, this is a very basic, low resolution test... does it really only go by 1.0 pH steps? does it measure beyond 7.0, to 8.0? It's accuracy is crude, and uncertain,..My point is, if this is offering anything useful,... do you not have a digital pH meter? Oh! wait, I forgot-- why don't you use the Accurate 8 meter? I told you not to worry about the roots,.. this direct measurement is more trustworthy than anything else! trust me dude,...
Fortunately, the plants are doing very well, mate!
... I see no sign of too high pH issues, which most likely would be Zn and Fe defc.'s,...
