New grower, same old problems. Input?

Hi everybody!
I'm a new member, but an existing lurker of the forums. This is my second grown and I'm starting to have some issues. I have been doing some research on it for a week, but to me it almost seems like maybe I've got multiple deficiencies going on? Or maybe something else entirely. So I'm at a frustrating end to the week on this and looking for more educated second opinion. This is a strain called "The White" and my room is sitting at 70 degrees, feeding water every 2-3 days as soil dries. Feeding nuts once a week (using age old organics @ 1/2 tbsp per gallon instead of the full tbsp called for). Damaged leaves can be found 2/3rds up the plant now. Does this kind of damage look familiar to anyone?

Oh yea, PH is currently 7

Just to some it up on most occasions its either ph , soil , and or watering to frequently which in soil can be the same as over-ferting.

My opinion is that they are in need of calcium and magnesium. Looks like some early N deficiency also. These are my opinions only and if my plants were doing what yours are this is where I'd look first

Thank you guys for responding! 240sxing I'm in complete agreement with your statement, although at this time I'm really looking for insights on which nutrient/s it might be deficient in specifically as the traits being presented are blurring the lines in my mind, on which deficiency it would be.
It indeed looked like cal/mag to me as well Jimmy. Specifically more on the mag side from what I was looking at. I have given her a couple doses of calmag. Last one being Wednesday last week. but to no avail, she's dying more and more every day and the damage has indeed progressed upward into it's once perfect fan leaves towards my buds.

More Nitrogen I will try for sure, I can see that restoring some of the color back to the leafs. Although after that I still have those weird spotty patches of what looks like necrosis developing.

Bring this down bro, bring this down.

It takes a while to see a change in a deficiency. As a rule what has happened in the past is seen on the older growth and what is currently happening is seen on the new growth. Don't touch your p.h 7 is fine .You need to explain exactly how much of what you are feeding and how much of that is available to the plant. Feeding every other watering can be necessary depending on what you are growing in and what your plants look like. Get a very clear and close pic of the whole plant especially the growing tips you are concerned about

Ever see any white fuzz or powder on your lower branches/leafs/top of dirt? Do you have good air movement in the room across the whole garden? In the last picture it appears overwatered. How long has it been flowering?
