The yellow on the last photo can possibly be pest pressure, but im not entirely sure. Best post this on a different channel like: Problems, Pests & Disease Control
Nice sized plant. Tell us more about it.
Is it a photo-period or auto-flower? Is it growing in a mineral soil or coco coir or something else? What fertilizer program are you following?
The 2nd photo does look like a possible insect problem but it could also be early signs of a Manganese deficiency which is different than the Magnesium found in a Cal-Mag product.
Is it occurring all over the plant?
Some leaves are affected, but adjacent blades/leaves are not so it looks like mites are first suspect to me
Cut off all affected leaves would be my best suggestion

Welcome to 420Magazine my friend.What can cause the leave to start turning yellow like this any ideas water about every 2 to 3 day
If I had to guess I'd say overwatered.
Every 2-3 days doesn't give time to dry and get air to the roots.
But we need details of what's in the pot and any thing else you can tell us.
Stay safe

Manganese deficiency if you ask me but then if should not be just on one leaf...I'd say if just one leaf then cut it off
At first look, I thought bugs, but after a closer examination of the picture, I don't think so. Really looks like leaf variegation, unless it progresses to other leaves, I'd do nothing. If it were a deficiency/lockout, I would expect more leaves to be affected, time will tell,

Couple had it i cut off and their a couple that its looks like its starting. Im thinking it locked out. Is distilled water a good water to give it
Your overwatering.
Let her dry for 3-4 days, then work on your dry cycle.

If you are thinking that it is a case of the plant being 'locked out' then it would be a good idea to answer the questions asked earlier. That way the growers who are using the same soils or fertilizers can help figure out if there is a deficiency or excess of any nutrient.
"Is it a photo-period or auto-flower? Is it growing in a mineral soil or coco coir or something else? What fertilizer program are you following?"
While the yellow spots on the leaves do look like the signs of deficiency of Manganese it very well could be an insect problem.
I grabbed one of your photos from the other message thread and one from this thread. I then concentrated on the area with the yellow markings, cropped out the excess and enlarged. Another cropping and it does look like the area on the fingers with all the yellow spots is bumps and no longer smooth like healthy leaves look.
Even on the same finger the further away from the yellow spots the smoother the surface looks. It might be time to insect the underside with a loupe or magnifying attachment for the camera to check for insects, their eggs or the frass (waste or feces).
