My system is flood and drain, I water them 2 times everyday, and I have been running this system, for two years. Will high humidity cause that?

What will be the best way to fix it if they are nutrient burn.

Drop your ppm check your pH flush with 1/4 strength nutes , can you give us a full run down of your grow it will help us better mate .od

Sealed room, ac with temp at 81, co2 at 1100, nut at 1100ppm. Didn’t pay attention at the humidity, cause I thought humidity wasn’t that important at the beginning of flower and I also left the dehumidifier unplugged by accident, so I am sure it was over 70%. I don’t know if high humidity would cause this problem.
I followed fox farm hydroponic feeding schedule plus cal mag and super thrieve. Per fox farm feeding schedule, stop grow big, add tiger bloom in week 3. I thought cause of missing the nitrogen, that was why start to get yellow. This is the first time I use fox farm. I used to use 3 part of general hydroponic.

Ok, thx, I am still following fox farm feeding schedule just added great white, coz only around 10 of of 100 plants are yellowing. The other are just healthy looking.

Can we get some whole plant pics.
What media is this?
How often are you flooding and for how long?
How are you mixing the nutrients?
Are you flushing from the top ever to get rid of buildup?
I think @cemchris has some experience with these nutrients
Think your ppm is to high. And you need to watch your humidity. It's very important, can you give some day night humidity readings

Whole plant pic? Size of pots and/or Medium?
Are you using the Foxfarm Grow Big Hydro (blue bottle) or the reg Grow Big (green bottle)? I ask because GB Hydro has Ca and Mg in it already. Reg GB doesnt and also has a lot of NH4 which will fuck with the medium PH. Specially if you arent doing top flushes in E&F in something like wool or coco as they get older.
The other thing is Tiger Bloom has calcium in it. Not sure of how much since they don't list it but it's in there since they use Cal nitrate in it. A tell tale sign is "Great for Tomatoes" which are Ca whores - the exact plant Calmg is actually made for. Whether it's actually good for tomatoes who knows. What rate are you mixing all the nutes per gallon?
Ive personally never liked their flower nutes. Just the Grow Big Hydro. Most people I know that run Tiger Bloom use it with PBP for Lucas.
High humidity problems usually pop up at the very top of the plant closest to the light. Ca is the first thing to get effected by that cause of transport issues. It's not the only issue but that's usually the first sign.

8x8x8 Coco cube
Flood 2x per day 10 mins each
I used the green bottle grow big but i
They started from the top ( I thought the light were too close, so I lifted up the lights and ignore the yellowing for little bit)
I didn’t flush at all ( never had to do it with general hydroponic)
I think I am going to fish them, should I just flush ( please recommend with resvior or pour water from the top) them with water and great white or anything you could recommend.
trimmed all bad leaves off, this was the pic when they just started.

Yeah green bottle is a no go for hydroponics. You will be fighting medium PH a bunch and just too much of a hassle to mess with. If I were you I would switch asap.

That is a good read on understanding the drawbacks of using the green grow big bottle. Also with understanding the labels when using nutes in hydroponics and what to look for. NH4 (ammonium) is used more for soil where microbes will break it down into N03 (nitrate - plant available N). Basically the green bottle is geared for stuff like Ocean Forest or Happy Frog. The ideal ratio of NH4 in hydroponics is 5-10% of total N. Green bottle grow big is pretty much 50/50 of that makeup in NH4.
Water level in E&F will get a nute buildup. Depending on how long you veg its a good idea to top flush when you change the rez assuming you are changing and not doing strict add backs the whole time. Usually around once a week. Sure any of that stuff will help but isn't "needed" per say. Just use fresh nutes on a change. I would never flush with plain water till the end.
You are getting away with flooding an 8in block of coco twice a day in flower? 6in white hydro pots (1 galish) on E&F was a good 3-4 times a day during flower with the lights on on for me in coco w/o perlite. More with perlite.
Try upping the fittings to 1in and maybe running a bigger pump if need be. Same with line to the pump and outlet to the pump. E&F shines in how quick the tables drain and fill. The quicker the better. This is just a suggestion for tuning E&F more and not required if not already doing that.

Hey jby , not sure if anyone mentioned the " super thrive " not sure of your dosage , but super thrive can create a nuclear disaster if used improperly ......

So what will you recommend to do ASAP other than switch the grow big. And I didn’t use microbe brew. What do you think about super thrieve, do you think it’s nessesary, or I can skip it.Yeah green bottle is a no go for hydroponics. You will be fighting medium PH a bunch and just too much of a hassle to mess with. If I were you I would switch asap.

Vit B is one of those things.... I don't use it. There are studies on it out there. Is it needed? No. Does it help? Ehhhh.
What are you currently feeding tiger bloom calmg and all that at per gallon or total ppm? What you are seeing is either the left over effects of the NH4 from the grow big, a Ca def from the nutes or enviro, or a P lockout of micros. Sorry can't really just point to 1 without a bunch more info. It could also be your aren't flooding enough.

I am feeding 15ml big bloom, 10 grow big, 2ml calm, 1ml super thrive, 4 ml signal per gallon. 1 table spoon of beastie bloom. My ppm is at 1200, I need to bump to that level cause my co2 ppm is at 1200. Currently temp 70/81 humidity is at 50%
