Hi Guys, I have a small issue with a few discovered leaves and hoping 1 of you guys can point me in the right direction. I'm thinking it's a magnesium deficiency but has only appeared on the larger fan leaves. I have removed the leaves to get a better picture.

Thats most likely Nitrogen (just beginning) being the most common and I dont see any feed schedule so just a guess.

The plants are overall happy, all fed from same reservoir in auto pots. Leaves taken from 1 plant only, smallest being from near the top. They are Sensi Blue Bullet Autos, week 7 from germination.

Magnesium deficiency normally shows with brown dots, had it a lot on hydro when I ran out of cal mag :P Looks more like a nutrient deficiency, If its lower leaves on the plant it can be normal, sometimes the lower leaves just turn a bit yellow at least I had that happen in many grows and it was pretty normal. How is the plant health overall ?
