Leaves turning yellow from the inside?

I suspect some kind of deficiency, iron, maybe sulfur. Either can cause yellowing leaves and mess with chlorophyll but that is an unusual yellowing pattern so I'm a bit puzzled. Are any other plants grown in the same environment, same soil and given the same water happy and green?

I do have other plants growing in the same soil and water and are very happy. I am not sure what is going on with this plant

I did a quick google and saw some plants that looked similar to yours and people suggested iron. Double check your ph and go from there

Another forum post said this which I thought may help
"

It really looks like Iron deficiency. It is yellowing on the new growth and has the yellow leaves with green veins (like Mg), but it starts from the stem and works its way to the tips. Mg def, goes the other way.

Your PH is fine, so the iron isn't getting locked out. Hmmm....

Check the iron content in your nutes.

Also, Iron reacts with potassium, so if you are heavy on potassium, that could show up as an iron def (or so I've read)."

Its been over a week and the plants growth has not slowed down one bit and the leaves are still very yellow in the middle of the vain. Not sure what is going on. It is suppose to be a Blue Dream clone and i doubt it is now.

that is pretty freaky. its in flower, when did you switch to bloom nutes?
it looks like you might be getting a little wind burn, the edges of the leaves are curling up a little.
the coloring does look like iron, but i've never seen anything make them fade from the central vein out before.
could also be sulfur, but again, thats a weird pattern
your light might be a little close, but if it was close enough to cause fading like that, the plant would already be crispy.
i dunno, if it don't get any worse, ignore it.

Being in early flower , you may have introduced bloom nutes a bit early.
There is definite fade of overall leaf color , as nitrogen may be too light.

Adjust your feed with veg nutes ( bump in nitro ) and allow plant to add a bit to its reserves. Problems occur when bloom nutes are introduced too early , i feed bloom at week 3 of flower .....
