Wtf, am I not feeding enough? help please.

K so I have a plant outside in a square 5 gallon pot of FFOF, the ph is fine, I've tested runoff and I ph my water every time.
Shes a few weeks into flowering now and around 4th week is when most problems start for people.
I've been feeding her fish emulsion (not the alaska stuff) of 4-1-1 as well as alaskan morbloom. (0-10-10)
I don't know if I'm overfeeding her but I doubt it. all of her upper growth is fine and new growth up top is fine.
The problem is that the lower leaves are yellowing at a decent pace and this includes the smaller ones too..
I'm almost thinking its a calcium deficiency but I'm not positive. Either that or more nitrogen? the leaves have some brown around the edges that sort of looks like P or K....I don't know.
Maybe I can get some help from you guys so I don't end up over feeding or destroying her trying to fix the problem the wrong way. here are some pics showing the leaves as well as the whole plant.

This looks similar to my problem, and I'm hoping/guessing it's N deficient. P deficiency at this stage of flowering would give us purple leaf stems.

Plants actually look pretty good, I would recommend upping your N nutes just a touch maybe 15%... but that would be max. Feed your plant when you can stick your finger about 1" into the dirt and its dry. With a plant that size, i am expecting the root mass to be huge so watering/feeding every 2-3 days depending on weather. Depending on your feeding schedule I would do something like feed-feed-water-feed-feed-water-1/2 strength feed thats a 7 day schedule... it works very very well for me and keep smy plants very green and happy.

Also, yellowing and dropping of lower leaves could just be the plant naturally getting rid of leaves that arent creating energy and have become useless.

what rev said u got yellowing starting from the tip down just up ur nitrogen and ur good mate other than that ur ladys are looking good

What about when upper fan leaves turn yellow all the sudden?, could going from Summer to Fall in 12 hours cause this?...sudden drop in temps from 60's down to 40's at night?.

Awesome thanks for the quick replies guys, I have a few more outside with her haha

Shes a pretty big girl, the tallest of my group, I'm 5'11 and shes about as tall as my nose.

I've overnuted plants before and to me its the worst thing ever, I feel like I'm killing my own children or something. I'd rather have them hungry than being burnt to death lol

heres a couple pics, this is my outdoor patio grow for the year, not too bad I don't think.
The one in the front row with the yellow leaves definitley had a P deficiency, purple stems on those yellow leafs, but she was fed today.
Theres a thread over in the outdoor section that I'm using as a journal, feel free to check it out if you want. https://www.rollitup.org/outdoor-growing/454005-meezys-2011-outdoor-patio-grow-3.html
