Welcome to RIU
Anything that already looks damaged will not change and look healthy.
The plant is at the hungriest part of it's life right now and for the next 3 to 4 weeks. If you flush and flush, you will starve the plant. I would add at least 1/2 strength nutes on next feed/water.
More info is better. What are grow media, nutrients, feed/water sched, ppm/ec, pH? What are temps and humidity like where you are?

Congratulations, You've got Russet Mites.

Get yourself a bottle of wettable sulfur, mix 1 tbsp with a few drops of water and make into a paste and then add it into a 32oz spray bottle of water. Spray your plant as thoroughly as possible, topside and bottoms of all leaves and all along the stems. Repeat again in 3 days. Then after another three days you can start rinsing the residue away with plain water.
Sulfur will be your most effective treatment at this point, otherwise you will be fighting a losing battle and might as well throw the plant away.
If anyone tells you the problem is something other than russet mites, they dont know what the fuck they are talking about.

Well...i recant my comment. Looks like @xtsho and @waterproof808 know what's up.
Thankfully, I haven't had to deal with russet mites before. Knock knock.

Its a good idea to treat your non-affected plants as well, and spray any nearby vegetation. Once you are in mid-flower you are fucked, but if you catch it early enough they are easy to control.
Luckily none of the other plants have been affected are you able to see these things
Great!!

I add 20% coarse perlite to any FF but agree it looks like mites. Small but visible in clusters with some magnification.

Look at the pic @xtsho posted. All that brown on the preflowers is literally thousands of mites in such high concentration they are making the plant look brown. If you look at the leaves that are curled, you will notice what look like tiny fibers on the leaves, those are mites.
If you want to be in horror, you can look at it with a scope, but I wouldnt waste time with that...i'd just rush out to the nearest store that had wettable sulfur dust and treat your plants ASAP. Only gonna set you back $10-15 for a bottle of it, but the most effective treatment until you are fully in flower.
Have you heard of pure crop? They say that kills russet mites and I have it

The ingredients are just corn and soybean oil, that they have some how modified its molecules to be more effective than a suffocant.
I've never used it personally but guessing from the mode of action described on their website, it sounds slower than sulfur dust, which works instantly.
Also, you should never apply sulfur dust right after applying an oil based treatment, it will burn your plants.
Russets work from the bottom up, so I'd carefully remove alot of those larfy lower branches and put them in a trash bag or burn it. Then do two sulfur treatments a few days apart. You should notice green new growth within a week of application. Since you are on the cusp of flower, its now or never, with sulfur. It is absolutely the most effective remedy for these bastards though, from personal experience.
