Situation

So I've been doing pretty good on my 3rd grow ever. BUT here I am about 3-4 weeks out from harvest for my auto(on right in pics) and she's starting to have fan leaf symptoms. First was 4 weeks ago, where new growth was very thin leaves and more light green/yellow than my usual solid green new growth; typical symptoms of PK excess. Anyways I didn't notice much stunting in growth because everyday I could see growth even if it was just sugar leaves looked bigger. Anyways after that I did 2 waterings where 30% of volume was milk - helps me fight acidity lock in soil...I believe lol. Then I did one watering with 1.5tbsp/gal pure epsom salts, because I saw fading interveinal green on 1 or 2 of the lower fan leaves on the auto. That was 2 weeks ago, haven't seen any interveinal chlorosis since. About week n half after that, 3 days ago after my normal feeding of Tiger Bloom 1.5tsp/gal with 1tsp/gal Big bloom, I noticed 2 or 3 orange/rusty spots on the fan leaves. "Uh-Oh, calcium deficiency" I thought. Which I believe I'm correct, but I know excess PK can cause mag/cal lockout...but the interveinal chlorosis hasn't progressed any so maybe its not that and just a plain by itself, cal deficiency. So this morning I crushed up 3 tums with only Calcium Carbonate 1000mg/ea, sprinkled them as a top dressing, and watered 1/2 gal w/molasses+1/2 dose Tiger bloom(1.5tsp/gal, bottle says 2-3). I think I'm 3-4 weeks out from chop day for the auto, so I really hope to see these calyx's swell some more.​

Being the OCD, maryjane loving fool I am, I believe I've thought of everything lol, but I wanted to throw it up here for any and all opinions. For learning and yield haha​

Looks like a calcium lockout from unbalanced nutes.. Probably too much mag..
Definitely not a deficiency with all you're feeding..

You’re adding wayyyy too much stuff and probably in the ring proportions I’m guessing. Tums?

Ring proportions?? No and my feeding is like this: water, feed tiger bloom and some big bloom, water, just tiger bloom, water, saw mag deficiency so epsom+water feed. And I pour it into a red cup, which I pour 2 or 3 - wait 15 min or so, pour again. Its never been all that stuff at one time....that's why I specified what I used when.
