CO2 Overload?

[Chato]

Hey all posted these pics in my other thread but i still need confirmation. Is this caused by CO2 overload? Does anyone one have any pics/links to CO2 burnt plants. If not CO2 what is it?

thanks

looks like the leaves are dried out at the tips, have you checked humidity and temp?

[Chato]

nothing has really changed in the room except the introduction of C02. I'm running the temps a little higher than b4 but with a/c it's not a prob. I thought it was more light burn at first as some leaves do look a little bleached but after moving and raising the lights it's not that and the prob is occuring in different parts of the plant that are shaded. So then i considered massive under-fert bc of CO2 uptake, fast growth etc but i upped the nutes and re-considered. looking closer it does seems to mainly affect the biggest leaves and it looks like it's fucking up photo-synthesis on the leaves. I don;'t have a flow meter for my CO2 so I can;t regulate it properly. I'll stop using it for a day or two and see what happens but i'd really appreciate some first-hand exp.

cheers

pic is a little deceiving, the tip of the leaf is a tiny tiny bit crispy unlike light burnt leaves which are fully crispy.

Try sending someone a PM like Eikel,tom, luke, or ferengi im sure they will know whats wrong with them

thanks for the advice man but I need some-one with CO2 experience

anybody........

What strength are you running your nutes at ??? How's your pH ??

 

Could be overfert but if the new growth tips don't have any yellowing/browning tips it aint that. Could be a pH related lockout/def if it's hitting the older growth - they are usually the first to show symptoms of ph related lockouts.

 

Sorry mate can't help with cO2 related issues - try pm'ing JackFrost on that one

definitely not over-fert and ph is steady 5.6- 5.7 after being a bit jumpy a few days ago so i flushed.

cheers

lights just come on, pic just taken. ppm 1050 ph 5.6. base water reads at 250-300ppm b4 butes. damage is worse closest too lights but also in semi-shaded and shaded areas.

Hey mate never had a co2 overload before, need 2 get yourself a good controller.

 

But before ya jump 2 conclusions make sure that nothing else is wrong and rule out this before continuing.

 

Is your ph within range? --yes

Is Ec to high? ---no

Are lights to close to plant?

Do i have scarid fly or any root rot?

Im i using a good quality fert?

 

Your plants look stressed mate? Would stop co2 and flush for a day or two with plain water and start nutes again.

 

sorry just reread your post - you have allready flushed!

 

If everything else is OK, there must be 2 much co2 in the room - get a 10dollar test kit 2 c how many ppm are in there. - usually over 2500ppm starts 2 damage plants
