Try some cal/mag or epsom salts if you have them. I have a similar issue and I'm pretty sure from all the research I've done that this is my issue as well.

I will be starting to use some epsom salts on my next watering, but your issue looks identical to mine.

Soil Ph levels are good at 6.5, dont mess with it.
Hit it up with some cal/mag and give it a couple days.

Looks like a Mg/K deficiency to me.
Both can get locked out due to high salinity, did you start small plants in a big pot?

Magnesium (Mg): this is a component of the chlorophyll molecule, it works with enzymes in the plant. Magnesium helps support healthy veins, and leaf production.

Abundance: Excessive levels will create a toxic amount of salts, that will inturn kill your leaves, and lock out calcium.

Deficiency: This is pretty easy to notice, green veins but fully yellow leaves. leaf tips can discolor and curl upwards. leaf edges can feel dry and crispy. the necrosis on the leaf will start at the edges, work all the way around the leaf. the tips will twist and turn, then the leaves will fall off without withering. *mag def is common with too acidic pH*
heres 3 pics of early-med-late deficiencies of magnesium:
