Lower leaves turning yellow/pale and drooping

I believe this is supposed to be signs of a nitrogen deficiency but I don’t see how that’s possible with me using full strength GH nutes, some lower leaves are turning yellowish/pale and drooping, the areas they are in are usually the middle/bottom of the plant, basically lower light areas. Feed about 3 times with nutes and then 1 time water and repeat, average night temp is about 74, average day temp a little hotter than I was aiming for with this summer heat, 80-82,and humidity stays between 40-50%. I’m like 2 1/2-3 weeks into 12/12.
***So basically I have a few middle and mostly bottom leaves in low light areas turning pale with a yellowish hue and drooping, I didn’t get a picture until after I trimmed them off the plant but my description is good I assure you. I tried to take a picture of the most yellow leaf to give a better idea and got one of the plant itself which is great minus the curling down on the very top leaves***

It looks like a nutrient deficiency maybe they’re blocking it out check your pH I would add some extra cal mag

if you leave big fanleaves without sufficiient light for some weeks and plant may decide to leech it out and discard it... I wouldn't worry much or increase feeds at all - your plants look well saturated in nutrition judging by their looks

My opnion...

Either your pH is not where it should be and your feeding your plants but your roots are locking out the nutrients which will turn to bigger problems later on

Or....

You are overwatering and thats causing the drooping leaves

I agree with Kassiopeija, your plants on the whole look nice and green so to me look healthy. Leaves that are lower down on the plant and don't receive much light will slowly die off, but i wouldn't worry about it too much, it's all a part of the natural plant process. If however your leaves higher up or on top start to go yellow then I would start to worry a bit and perhaps look in to a deficiency of some type. You're Looking good at the moment though.
