Thanks, bro.
So I flushed everything to a minimal ppm runoff, can I now expect the salt buildup to now be alleviated, and will I see the leaves begin to point upward?
Is this a copper deficiency, and should it be flushed?

If your gonna use Blumats with nutes always and coco coir...you don't get runoff. And I know a lot of people get away with it but you really need to feed in the 1.0 to 1.6 range tops if your gonna go the Blumat route. And once a week use a mild and pH balanced (1.0 EC & 6.0 pH) feed using a pump/tank and simple water wand on the shower head spray setting. My buddy uses Blumats and this is how he does it with no problems. Spray them pots down with the wand once a week manually until about 30% of what you sprayed comes out the bottom and ditch this junk. Start doing it on your next run once the plants are established in final pot and have a nice anchored and well established root system. You should be good to go.

And get your lights off temp up bro. 55 is way too low unless your doing it on purpose towards the end. Get a small heater in there that turns on when lights kick off. Make sure your outlet/timer/extension cord (If you absolutely have to use an extension cord) can handle the power a small space heater dishes out so you won't burn your frikin house down!!! But at anyrate..get them night temps up. Freel

no idea bud. im sure they will perk up a bit but there is a lot of damage. i doubt if they pray again before you harvest. if you were still in veg i would say yes the new growth should come in healthy and perky

Why do carbonates in water make any difference to coco, seriously some basic chemistry will tell you that your water provides zero available cal and mag so your not actually supplementing anything, stoner myth here, dont believe the hype or bother wasting money on stuff that should be in every fert.
Again i was merely suggesting ways to counter the high salt index.

he knows his problem. 5500 ppm of salt build up and low night time tempsRuh-roh, you mentioned flushing. That's like yelling Hi Jack! at an airport security checkpoint.
@Dr. Who would warn you that flushing without knowing what is causing it could cause more harm than good, for example.

Weekly water wand flushing with mild pH adjusted nutrient solution as a preventative for salt build up is a whole different dealy. And good practice if your using Blumats or a drip system where your not getting runoff consistently.Ruh-roh, you mentioned flushing. That's like yelling Hi Jack! at an airport security checkpoint.

Since using coco, which is all I have ever used, I have encountered these crazy salt buildups every time.
I’ve used different nutrients. I’ve dropped recommended nutrients to less than 1/2, sometimes as little as 1/3, and still get the buildups.
I’ve watered by hand to weight of pot. I’ve watered by hand daily. I’ve watered by hand to daily runoff. I’ve used Blumats. Every time I get these crazy salt buildups.
The only thing that remains the same is the coco.

Also, that 55 temp was about a 2-3 day deal, my low temps have been consistently around 63’ish.

Salt build ups is one thing. Salt build ups and a fukt up plant because of it is something different all together. I wouldn't change a thing if a meter said I had high ppm on a return if the plant is jamming and looking good.

you HAVE to get some run off in coco, or the salts will build up and eat your roots. at least once a week you NEED to top water till you get a little run off.

Yikes! Your plants were looking good awhile ago. I seriously don't know why you are having so many issues. Just to speculate I would say you overfed and the temps got too low. I've never had issues like your experiencing using blumats and 100% coco. I stay under 800 ppm, sometimes a little more but not by much and the 800 ppm level is during the first few weeks of flower. I start cutting back mid flower. I never flush or top water. I also use a small space heater in my tent to keep the temps up during lights off and I run the lights at night when it's colder letting the light heat the tent. The space heater runs during the day when the lights are off and it's warmed up enough that the space heater keeps the tent around 68 - 70 degrees.
Those plants are not going to recover significantly by harvest time. I hate to say it but those buds are not likely to get much bigger. Those plants are stressed out, overfed, and likely drowning in that soaking wet coco after all the water you flushed through. Never flush straight water through coco this late into a grow. It screws things up. I don't think you have enough time for those to recover significantly. You're too far along. If I were you I would yank out the blumats and hand water for the remainder of the grow with 1/4 strength nutrients.
That's pretty much all I can offer. You seem to have so many issues and as soon as you fix one another pops up. I think your cursed. Just joking but man you sure have a bunch of issues. Sorry not to be of more help but it really doesn't matter that much at this point. Those plants are already screwed. Are you positive your giving us the whole story on what you have been feeding?
