Maybe. But phosphorus deficiency is apparent too.
Is the yellowing of the leaf edges the sign of phosphorus deficiency? Hard for a new guy to see what the leaves are starting to say here. I’ve been feeding advanced nutrients 3 part but only in half doses. Worried about over doing it using the liquid nutes for the first time.

Likely underfeeding. It's confusing to pin point only 1 deficiency when multiple nutrient deficiencies are showing.

Next learn up on pH in your medium, feeds and water. Giving what it's lacking in tissues does not mean it can be readily absorbed if pH is off. It's simple stuff that will have you growing kine bud every grow.
Yup just under feeding it seems, I had been going pretty light on the liquid nutrients because I was worried about overdoing it. I’ve been on my ph though. Water going in is always between 6.1-6.4. Have done some runoff/slurry tests and they’ve come out about 6.7
Curious what deficiency’s you were seeing in the leaves in the photo, you said there were multiple, could be a good learning moment for me.
Thanks

This will help you ask better questions and give you answers to what you are seeing. Start with these as they are the usual culprits of chlorosis. Look at the leaf that catches your eye. Note the pattern and color changes from healthy vibrant green. Note if it's droopy, straight, curled etc. Note if new growth or old growth affected. Then look at the overall appearance of the plant.
