Lower fan leaves dying halfway through flowering

The title says it all as well as upper fan leaves. It looks like a Nitrogen deficiency, but I still have 5-6 more weeks to go. I’m on Week 5, so it’s not too too late, but I’m wondering should I do have the amount or double the amount of the flowering nutes? I use organic fish emulsion at 2-4-1. The Veg nutes are 4-2-1. What do y’all think?

I've been experiencing some N def at about the same time as your did, I hit mine with a 2-8-4 and it perked right on up. Going to wait another 2 waterings and probably do it again just to make sure it is good for the rest of the time.

So don’t give it nutrients with nigher Nitrogen

From my very limited experience, I wouldn't. I locked my first batch out while in flower due too much N and that was running the recommended dose of my flowering nutes. I have since learned that about 3/4 of recommended dose works well for me.

I think it’s because I’m not watering enough, I may have to water every single day. The thing that’s crazy is it’s in a 2 gallon pot in a PC Tower, so the root structure must be huge to be dry everyday

Check your ph also. 5.5 to 6.5. I would leaner closer to the 6.5 during flower and veg the 5.5 ph. Plants wont intake any nuts if ph is off.

Unless he is in coco, perlite, or some other type of media that is essentially hydroponics, under 6.0 at any phase of development (or possibly even under 6.5) is going to have a negative impact on nute uptake. 5.5 to 6.5 is indeed optimal...for hydroponics and coco....
