Please tell me why the veins of the leaves are so yellow!?
Please tell me why the veins of the leaves are so yellow!? what could it be? zinc block or cal-mag shortage ? pH all the time was 6.3-6.5, EC first was 0.7 today when I saw the yellowness on the leaves I lowered the EC to 0.5

Yellowing
Hi! It looks like my grandaddy purple is starting to yellow, in my last week of veg (7). Could it be caused by too small of a pot (3gallons), this is my 4th grow, first time growing only one plant using scrog. Maybe an upgraded pot before I flower? Thanks!

What is happening to my plants?
I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.

Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

Yellow lower leaves
Lower leaves are turning yellow. She just started her second week in flower. My first thought is I'm not feeding enough. She is short, but still a lot of plant here. Here upper leaves are a nice shade of green. She prays all day long. Is this a problem.

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.
