Just got tagged back in.

Took a look at your last pics on pg 3.

The first answer I gave has a new subsection......I thought I saw it starting there but guessed it would calm down some - nope!

You have a pH problem starting there! Low most likely. What are you in? Use a Ca/Mg product?

Yes I thought that's what has happened. But the solution is the same. Fresh water to wash out the idle salts and a lighter nute solution of a balanced ratio. Not a hydro bloom solution. And no boosters.

@Dr. Who thanks again for the input

PH tend to go high quick this run.
Usually it takes a week or two for ph raise from 5.8 to 6.5. This run only takes three days. My ph
I'm using maxibloom with liquid kool bloom. With some cal/mag and b52.

I also realized EC go up quick too. 1.3 to 1.5 in a day.
Now I drop res EC to 1.2
I will have my res change tomorrow. Not sure what nutes solution should I add in.
I ususally use MaxiBloom and powder Koolbloom in last two or three week flowering.

Plants should harvest about three weeks, do you mean I flush my system right now?
I though this is an important stage of grow. plants should get nutes to push buds grow bigger.
If using fresh water in res, Do I add nutes back or I flush till the end?

cheers

No flush. I don't even like that term. I am suggesting some fresh water to clean out the medium a bit. And then a lighter dose of grow style balanced nutes. I always taper off the nutes the last few waterings. But if they are still growing and need them they get them. But realize their needs reduce as they ripen.

thanks for the quick reply man! I will lower the EC, just use base nutes and some cal/mag. no Blooster hope that can help them not getting worst.

I also wonder whats the exact time for cut off co2? I heard its around two weeks.
Is there any specifically sign that tells when to cut it off?
Also I have two stains growing in the same tent. One chop around 58 days and another its 65 days.
If I cut gas early the other one will have three weeks without co2 before chop off.
would that be alright??

Sorry for that much questions...
I thought Im alright for vent style grow, so want to try co2 and expect better result.
be bad that I think Im not good to control all the environment in order to rock co2 well.
but I like sealed room with no oder vent out.
Im sure Im going to find the way to rock co2 well
again, thanks for all the tips and feedbacks here
happy grow

I have no experience with co2. I have only set up vented rooms.

But, extra co2 can only benefit your plants if the photosynthesis is already maxed out from everything being optimal. And it requires very high light intensity to show results and a comparatively higher temp and humidity.

As far as I have researched.

And I use carbon filters for my flower room exhaust and drying closet. Admittedly my house may smell from smoking a bit but no one has noticed any smell inside or outside that would cause suspicion.

But if security is life or death I too would build a sealed room. Less risk. I would probably scub the room I went in and out while working too.

But I am a legal medical patient in compliance.

YES, you MUST stop Co2 use at least 2 weeks before harvest! Co2 inhibits ethylene gas formation - that's what ripens the buds - the ethylene gas!....Drop gas at the start of week 6 to be safe! There is NO "sign" the plant gives you! It's all day counts on this!

As far as differing plants maturing at differing times. You made that call.....stop as your supposed to! Your not going to loose as much as you think on the other one.

Um, how did you make a call so defined as 58 days? Are you sure the plant is exactly at the same place on the same day as the last run? I doubt it!

Legal medical patient...I'm so jealous man...

When u said drop gas when week 6. What ppm are you talking about? My tent stay 1200 highest when below 800 burner kick on.

I'm not sure it will be same day. I assumed it's somewhere around 58 days. I use scope to see how trichom turn before I chop.

I ran at 1300 as above that, the return slopes out at a sharp bell curve value.
You want it OFF at 6 weeks! It has to be at ambient or natural ambient levels!

That 800 is too much...just shut the whole system down at 6!

@Dr. Who
I also wonder when cut off gas at end of two week. Do I need air exchange for the room?
Or I just keep room closed with A/C blowing would be fine?
 

Dr. Who

Yes they will still need some new air - if the AC is exchanging air with the outside, that will work....If the AC is a minisplit or Central. Your going to need to exchange it somehow.

Good day @Dr. Who
I cut the gas today.
I use mini spilt A/C. I setup an exhaust fan for the room turn on 15 mins every hour.

At this late stage when cut off gas, do I still keep my room temp high?
my tent temp when light on 83-85. when light off 75-76

@Dr. Who
Do you have any experienced with grow tent with bruner out of the tent?
set an intake fan under the burner, and exhuast for the tent to keep air exchange.
I see Co2 ppm raise up when controller shutdown burner.
I set controller shut burner wen hit 800ppm. I go up to 1200 in few mins and remain that till plants use it out.
I wonder 800-1200ppm range when lights on could be the reason plants dont look healthy in this entire run?

Sorry for that much question...really do appreciate your help
have a nice day

Yes, lower temps.

It's the gas settling - Co2 is heavier then air. What height is the sensor on the controller set?

Look back at my all thread, seems like Im still having same problem.
with CO2
@Dr. Who I changed the feeding schedule, leaves still turned yellow and stuuned
Any other factor could cause this problem?

I have the same setup instead on burner, I just venting air out of the room. It work great
There must be something I missed by using CO2.

any feedback would be really appreciated
cheers
