Hello, this is my first grow i am currently pretty late into the grow at 11 weeks total looking for advice on what to do atp. plants have been flowering for about 5.5-6 weeks (i got them from MSNL and the site says <8 weeks flower for white widow and 6-8 weeks flower for thc bomb). in the photos, the white widow in the one in the front (closest to door of tent) and the thc bombs are the two in the back. I can pretty easily tell the white widow is not as far along as it just has not put on as much weigh as the two thc bombs. I've been watering with the attached water schedule 2x per day to 25% runoff (i only water with nutes bc theyre in coco coir). I'm wondering if these look like i should start the one week flush now or in another week? trichomes look pretty clear all around but im just using a jewlers loupe and it can be a bit hard to tell. what i'm wondering is should i continue watering like normal for another week for two for the thc bombs / white widow / both or start the week long flush in a few days? and if so, should i make any alternations to the nute levels in the water or just repeat week 11 until theyre ready? Also the plants have what either appears to be a magnesium / potassium deficency as some colas have red stems or leaves that are yellowing / turning purplish with spots. the plants got some light burn around week 6 which is why some of the taller parts have some dryer leaves. also some of the stems are starting weighed down in parts where the buds are getting too heavy for the stems which indicates to me its getting closeish? I know people usually see things like nutrient burn etc towards the end of their grows due to buidlup or other things, but is this a out - of - the ordinary level situation where i should be worrying more bc bud quality will get compromised or something? any and all help / advice is greatly appreciated.
new grower looking for advice on chopping / flushing and late flower nute burnout / deficency THC bomb and White Widow (autos)

First thing, disregard what the breeder timeline says, it’s almost always longer. You’ve definitely got some nutrient issues, have you flushed the coco to get rid of built up salts? If not, run plain water through the plants till you get 100% runoff, then go back to your week 11 schedule. Looks to me like the salts may have locked out a number of nutes.
okay makes sense, i did that awhile back but just once how many days / watering times should i flush the plants for til i restart nutes? ty

Dump water, two to three times the volume of the pot through it, all at one time, then you can immediately go back to feeding.

If you have an ec meter measure what's going in and what's coming out.
If its very high coming out flush about 10x volume of the pot.
Then feed normally.
Make sure you ph is 5.8- 6.2.
Then continue to feed normally until you are ready to chop.

ok i do not have one of those but i flushed them so i will be going back to nutes, when i am ready to chop, i should flush the plants right? ive seen online a lot of people usually do it a week before chopping. so i should expect about 1-3 weeks of normal nute schedule plus another week for flushing or just chop whenever they're ready? thanks so much

No problem, just feed up until the day you chop.
Flushing at the end doesn't do anything.
i see i see, bc i was told flushing takes the nutes out of the bud and makes them taste better but that makes sense and sounds easier, will do fs!

This is a long but very informative video which is the result of someone's dissertation toward getting their doctorate.
There's a lot of info in there, it does go into flushing. But it's all interesting.
Thought I'd post it as its neutral, as opposed to some of the other studies which prove flushing at the end of the plants life is pointless
