Possible nutrient problems

I am growing Bubba Kush indoors. It is about 6 weeks old and I am starting to see some leaf discrepancies. I am trying to add some pics. I am thinking potassium and magnesium shortage. Your thoughts concerning this are welcomed.

Looks to be new growth, which kind of leads me to a micronutrient. To start with, Ph needs to be in a good range for nutrient absorption, what is the input Ph of the water / nutes? Nice big leaves on those plants

Not seeing anything critical.
Can you give us some more info on what you're feeding them?

Root issue, PH low or high causes nutrients to not be taken up.
As said need more info!
