Thats what it looks like too me.....Potassium (K):
a.k.a. potash, this nutrient is key for the usage of carbs/sugars. This is key for sturdy/thick stems, small bushy plants and disease resistance. Its needed for all stages of plant growth, especially bud formation.
Abundance: this is pretty rare to notice, excess potassium usually isnt absorbed by the plants but can mess with levels of magnesium, manganese zinc and iron. This in turn leads to salt damage acid fluctuations and possibly a calcium deficiency
Deficiency: this has yellowing of leaves, from outside in, but with a dark green center vein, and curling of leaf tips, this is mistakenly diagnosed as nitrogen def or iron def a LOT. Stems and branches will be weak, easily broken. the plant may also stretch. *too much sodium (NA) can cause a potassium deficiency.

well it is just the regular potting mix. actually the pot the plant is in I believe is the moisture control bag. not sure if it makes much differenece. I am thinking from now on of using regular dirt and then adding my own nutes.
Reading run off pH as an indicator of a mediums pH is total myth and useless.
Pics would help, but it sounds like they need some food........
That late stage N def pic is not accurate. The veins yellow in proportion to margin yellowing when it comes to n def. That pic clearly shows green vein petiole too tip....Put on a blindfold, get a dart, and throw it at this chart.
Good luck.
Edit:
My guess is you have early stages of N or Mag deficiency. Giving your plant a little calmag wouldn't be a bad idea.
I was high when I colored it.
