Thanks for post Jdog2020could be... you also have badly purpled stems which is a sign of Phos def, most commonly associated with pH lock out... (and probably the most common problem I see in this section besides heat stress)
maybe try popping the plants out of the pots and looking at the root mass... see if its curling round n round itself...
you guys should also know that some strains nearly always display these red/purple stems (they're just phos hungry) the UK Cheese is a good example of that, it nearly always gets red stems...
the pH 6.5-7 in soil is bang on mate...
good luck
