Please help identify what stress(with pics)

Good day RIU,
This is my first time running co2. I realized that the surface of leaves look different than without adding co2. Is that normal?
When running vent grow. The surface looks more glossy, and now is coarse.

They are in three weeks of flowering.
I also found the color of leaves is also slightly lighter than usual.





Anyone if you know what am I missing to cause this pls let me know
Really appreciate that
Cheers

What are you feeding and when did you start feeding that feed?

Bet you started "bloom" nutrients at the flip,,right?

Bad idea! You've got a sativa dominate strain and those tend to be fussy with feeding anyway.

The deal is you started too high a P&K value and lowered the N value when you changed to "bloom" nutes.

Next time-----Don't start bloom nutes at the flip. Run your VEG nutes for 2 weeks after the light time change and for the 3rd week do veg and bloom mixed 50/50 and at week 4 go 100% bloom nutes.

Not much you can do now. maybe add some N and hope that slows down the progression some....

I've had problems like this when I change strains , and also when my ph meter was broken and I didn't know it . And I tried to grow blue dream a sativia dominate, that looked a lot like that, it all started after flip to bloom nutes so I completely agree with Dr Who ( he is sooo smart ) mad respect for that dude
Peace out bare

 

[ligrow]

@Dr. Who @Bareback much appreciate for the feedback.
I did start use bloom nutes at soon as I flip.
I went half veg half bloom at the time.
After two weeks it's all bloom right now.

the surface of leaves looks different than not adding co2 normal? I'm not sure if they were 100% healthy at veg stage tho...

Really new to co2...had def in veg stage.
Dr. Who also threw some really helpful input. Again thanks for sharing your knowledge!
Cheers

I quite using co2 because it's too hard for me to control heat and spray. I keep venting off all the juice. For me co2 was bell or whistle and not a requirement.

 

[ligrow]

Yes, I done vent grow couple times. I'm my location need A/C runing more than half year. I found mini spilt is the way to save some bill than others. I did some research and lot of ppl say if using mini spilt why not adding co2. So I'm here...
I also have another room using window a/c without adding co2. It's easier for me to my everything under control.
But I like running sealed room
no venting= no ordor outside
I'm going to figure is out hopefully I can have it all sealed up with co2 in the future.

I'm still confused about co2 in veg stage.
If I'm not wrong. I remember @Dr. Who mentioned no need co2 in veg stage. I see lots of ppl using it from veg to end of two weeks. If not adding co2 in veg stage, when do I use it? As soon as I flip?

Happy grow guys

But to actually make the Co2 effective or work properly. You need to run your temps at about 90 and the RH at 70%! Heat should not really be an issue!

Quite correct! NO gassing in veg......You don't get any good cost to result ratio!

Thanks Dr who that's good to know I might try it again. After all I already bought it right. Can you point me to some info on how and when to spray properly.
Peace out Bare

Once you start using Co2 you are pushing your plants production. Meaning they are using more nutrients than normal. Are you using any boosters? Usually it is an Iron problem but could be something different. I see slight burn on tips of leaves and the veins are yellowing as well. That is usually Iron.

Im using maxibloom for based nutes.
Did add Koolbloom liquid for booster. Also have some B-52 and Cal-mag.
You think the burning tips its from Iron Def? How to I correct this problem in your view?

WRONG!

That's not an Iron def!
Iron defs start to show at the core of the new growth. The higher up the plant, the more pronounced it shows. (Same for Sulfur defs ! S def is more yellow looking and Ir defs more white or less yellow then S. They tend to happen together in MM as I've seen them mostly from pH imbalance and blocking uptake.)

Too much P too early! PERIOD!

What equipment do you have to gas with?

What were you reading? I said it could be a iron def.. and it usually is Iron
Looks like you missed the part where I said it could be something different.. I never said It's definitely an Iron deficiency.
Wow little ego there. lol..
By the way. P toxicity will leave the veins of the leaves green still. So if you feel the need to push the ego on someone. Do it to the guy in the mirror with to much pride where he thinks he has to put others down to make himself look like the winner of whatever competition hes running..

are you kidding me?? Running temps that high drops Photosynthesis dramatically. You are way off there on your information. Some plants like it between 50-68 degrees F. 90 is way to high for any plant

The actual optimum temp for plant photosynthesis is between 68-86 degrees F.. Going over drops the Photosynthesis curve like a rock.

Boy you sure know your stuff don't you.. I would hate to see what your plants look like.

I simply said it was NOT an iron def. eliminating it as a problem.
By adding "possible" problems - You only confuse new and sometimes novice growers, distracting them from the real problem!

I also outlined just what and how "actual" Iron def looks and express's like! That's information! Not a slap to your thin skin!

As to the last comment on P tox......Only at an early stage of P tox expression. Advanced case's get leaves completely yellow, and that can happen fast as per the strength or if it's being continued in use, thus increasing the problem on a bell curve.

If I was to insult you, I would be very specific. Trust me, I haven't,,yet.

Yes Add Nitrogen in transition.. LOL. Where do you get your information? Up your nute strength with N another add that can burn your plants.. wtf are you smoking. Cuz it aint your own stuff.

Ah, I see! You don't actually know SHIT about gassing do you?
I suggest you do some googling for info on actually using CO2 properly!
Maybe read Ed Rosenthals book Marijuana Growers Hand Book! Whole section of just how to use gas properly!

What a sadly weak attack to help cool your butt hurt!

You obviously have no idea what you are talking about. I run my sealed room easy @90º, thanks co2. Newb

Butt Hurt getting worse? Who's ego is actually hurt here? Not mine!

Can tell I've been growing longer then you've been alive,,,simply by the way you answer!

Look kiddo, your only digging yourself a deeper hole!
Stop while you can still climb out..
