Co2 3500 ppm

[Diyandimitrov]

So something went wrong last night and caught my room with 3500 ppm co2 at night time but probably it was also when the lights was on I'm not sure I'm just guessing. My question it's can 3500 at night time mess with my roots cause today I see some dry leaves on the bottom of my plants I think that happened over night. I will send you pictures later.so my theory it's thw co2 it's heavy then oxygen and go down and kind a chock my roots to breath at night time.but that's just theories. What it's your guys opinion

 

[Diyandimitrov]

What it can be ? Soil too dry or that co2 issue

 

[013]

Never ran co2 but would think it would pool up in the floor not in your plant trays

Lemme phone a friend @bluter @Bill284

 

[Diyandimitrov]

They looks nice and green on the top I think?

Good morning my friend @Diyandimitrov keeping busy as usual I see.
First that's way too much co2 for you to be around.
Hope you cleared the room before going in.
Never ran above 2000 but 3500 isn't horrendous depending on length of time.
Couple hours won't hurt.
I don't think a little extra co2 did any harm.
If you still have leaf issues still it's not a because of co2 last night.
Could it be older damaged leaves just drying out?

Stay safe

Can be foliar spray versus spider mites I start to assume about that also.but why to it's only the bottom

 

[Bill284]

Nitrogen and potassium deficiencies start on lower older leaves.

c02 is a total waste of money in a grow that size. hope you're spending lots.

it's looking like a nute issue, with the plants bottled up in a bucket that is too small, and a room that wasn't flipped on time.

get it flipped, get on top of the nutes, hang on and hope like hell. things look great right now, but i suspect all the trouble is coming in flower.

Hopefully will be fine. They are like 24 inches tall and I don't even water them every day yet I mean they don't need water that often cause the pot don't dry every day. I water them every other day the biggest one the smallest every third day so what I heard if they don't dry every day they are in the right size pot. Correct me if I'm wrong but in the end of flowering I hope to water the every day cause they will be big enough to drink all the water. I flip them tomorrow anyway. Should I go 12 12 or 36 hours only darkness.

I like 36 hr darkness to kick off the hormones that cause flowering.
Good way to start.
Your in Bx right needs feed-water-feed-water every day to run off at 5.8.
Your not supposed to let it dry.
Your coco is to be fed every day with nutrients at 5.8, also never let it dry.
Or give any water in your coco rooms.
Get them into flower asap before you run out of room.

Stay safe

How bad it is ?

 

[BeccaBuds]

They are definitely root-bound. Up-potting would increase yield a lot.

Here's what a US govt website says (courtesy of Google) about risk levels for CO2 exposure for people, not plants, but the risks must be comparable:

The American Conference of Governmental Industrial Hygienists (ACGIH) recommends an 8- hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for a 10-minute period. A value of 40,000 is considered immediately dangerous to life and health (IDLH value).

That said, I've heard of people that have sealed their grow and filled it with CO2 for a period (don't have the details) to kill off insects (it doesn't kill the eggs, though). Supposedly harmless to the plants with limited time exposure.

And how bad it's to make clones from the plants I planing to flip ? I mean make a clones and flip them next day? It's bad or doesn't matter

That fine absolutely.
I clean bottoms off before flip all the time.
Make a bunch of clones from everything I clean off.

U like to cut my clones from the top of my plants usually

 

[Diyandimitrov]

I mean I like to cut them from the top sry for my English

I find bottoms root quicker.

I take cuttings from plants I plan on flowering all the time. I have taken some cuttings a week after "the flip".

In my opinion it will be a waste of time and money unless you first spend some time fixing the problem that started this thread to begin with. Putting the plants into the flowering stage will not make the problem go away. Popping the plants out of their pots to admire the roots will not fix that problem. Taking cuttings so that you can try to root clones will not make the problem go away. Trying to avoid fixing the problem will not make it go away.

Still my opinion but putting the plants into a flowering light schedule will make the problem permanent because once flowering starts there will be no way to go back and try again.

@bluter and @Bill284 and @beccabuds have already given you some expert advice. You should be working on that info now and not the other stuff.

 

[bluter]

looks like a 3 gal bucket or so. should have been flipped 2 - 3 wks ago. that's about the root bound i wanna see near the end of flower. not going in to it.

you could up pot and clean them up but you're looking at extending a good 2 wks or so. your call. it's also more work than you needed to do.

with photos i take clones the same day i flip the light sched. you can take them up to 2 wks after, but they will have to reveg and won't take so well.


you shoulda just mailed me the money for the c02. at least i wouldn't have wasted it.

clean them up as best you can and flip.


you're watering all wrong for the media as well. but again you got horseshoes.

it's right in my link and i suggested it earlier though you couldn't bother to read it

The Proper Way To Water A Potted Plant

The Proper Way to Water a Potted Plant Also covered: the importance of pH and why we successively up-pot How to Water Over the last several years I have put a lot of study into this, and I feel that I can now define the proper way to water a potted plant. Keep in mind that this discussion...

www.420magazine.com

read it and live by that in your current media.

edit : that's for the hp.

the coco is all together different. you can keep the current approach for the coco. i'd ammend it somewhat but it will work. i'd feed the coco either every day or mutiple times in smaller amounts if you are automated.

 

[Diyandimitrov]

How much I should go for hydroponic.or.media application? That's confusing me.
