What in the world is going on!?

I'm at 8 weeks on the nose of flower with two WW plants. These symptoms have been rapidly increasing over the last few weeks but started about mid flower (week 4). One plant has more more pronounced symptoms but same issues as the other. My guess was nute burn as I'm using FFOF soil and added the liquid trifecta halfway through veg. Measured the nutes as instructed on the labels but I've learned that this is possibly way too much. Used bushdoctor a couple times throughout the grow to clear away excess nutrients(at least that's what I thought I was doing). Always PH'd my RO water when feeding. Used nutes every other water. Anyway I added cal mag when I noticed these symptoms cropping up 4 weeks into flower. Been feeding it ph'd reverse osmosis water for the past week. I'm posting because I've searched the internet up and down and have not seen any pictures quite like this. The trichomes are dying off the sugar leaves where that brown rustiness is showing up. No rusty residue when I touch those spots with my finger. The "infected" leaves seem a little dry but still strong and def not crispy or breaking off. Running a single LED about 20 in from plants and is hitting the top colas at around 600 lux. Got red and blue switches flipped on for flower. 12/12. Possibly light burn? Environment seems good but then again I'm a new grower. Lower fan leaves have yellow and rusty spotting as well. very dark green leaves. Questions are, can I leave it flowering for a little bit longer or chop immediately? Should I chop every "infected" sugar leaf off now? Can I do a dry trim which is what I wish to do? Basically, what are my options? Thanks in advance!
(my email is being a real B right now it's not letting me email pics of the fan leaves I will post when I figure this out. Thanks in advance everyone!

Mine was way worse than that I would let it ride and dry trim
I wouldn’t let it go too much longer tho or it will start looking like mine did
 
You guys are the best I’m already glad I joined. Here are photos with led off only I wasn’t able to use my nice camera this is my phone camera hope this’ll do. I’m most curious about the trichome death or disappearance at the really gnarly brown parts of the sugar leaves.

When do you plan on chopping her down she looks ready
 
Flush why?
Because if it’s nutrient burn I want to continue with straight water as I have been and get as much out as possible before chop? Also I want a little more amber which means I’m watering tomorrow anyway. I won’t be doing an insane system flush with bush doctor or anything like that. Is this a bad idea? I don’t mean to presume but as far as the flush or not to flush debate I have no interest in taking part in it I’ve read every debate in and out of this forum and I’ve decided I would like to run water through my plant for the last week or so before chop. ESPECIALLY if it’s nutrient burn. Maybe when I’m more experienced at this I’ll do differently. But I’m happy to hear what you have to say because I’m new at this and here to learn. Thanks!

No... do whatever you want to do. It's your grow. I will tell you though, that you can only flush your media. You cannot flush the plant. The nutrients in the plant are there to stay. The only time nutrients come out of the plant is when the plant ec is higher than the media ec, which is a bad thing. On this forum, you can only get the information. Some are right, some are wrong, you have to do the homework and figure out which is which. What you decide to do with it is up to you, but never stop learning. I don't like to argue either, though sometimes I do. :bigjoint:

All this is only my opinion though. Remember... do your homework.

Hey Holla I’m still trying to understand your take on this, is it your opinion that using plain water to remove nutrients in the soil so that the plants are forced to use up their reserve nutrients is a myth? And I guess this is a more scientific question now because I admit I don’t understand the excretory process of plants but I’m assuming it’s much like any other biological process, and when the plants “use” up nutrients in only assuming they have waste pathways that get rid of unuseful compounds.

I do believe that, yes. I grow in hydro, so my plants are basically force fed nutes, I've never flushed and never noticed a difference from flushed. There was a study done. It's on Migro's YouTube channel.

Sweet I def haven’t seen that study I’ll check it out. Any thoughts about what’s going on with my plant?

i just watched the study and it was fantastic I no longer believe in flushing for the sake of flavor and bud quality. The main questions/other takeaways for me are that 1. I would like to see the study expanded to different brands of nutrients ie organic/inorganic as well as different amounts fed. 2. Flushing is actually good because there’s no diff in it so you might as well save the extra nutes. 3. I’d like to see studies involving diff media because the top interviewee mentioned that coco actually absorbs the nutes over time so it was possible that it was still feeding the plants rather than washing the nutes away. However this seems fairly negligible. This study also raises diff implications regarding nute burn and solutions for that. Anyway, thanks again.

And if anyone else is reading this I still would like to know what the hell is going on with my plants. ph before feed and after runoff was always correct or corrected within one feeding. Although I don’t have a soil tester so I’m not 100 percent on that. Only tested runoff...

Most will tell you runoff measurements mean nothing. I'm not exactly sure on that one, my runoff ph on my mom's is usually right around the same as I put in.
