Potential CO2 damage? Or something else?
hooolianstarted grow question 9 months ago
Installed a Carbon Bag two nights ago - and they are now on 12/12 light schedule as of yesterday these are the only things that have changed. - No sign of pests - what are these strange marks on the leaves? All four plants have grown rapidly over the past two days aswell

High bro, the cause for this symptom is due a magnesium deficiency. And the magnesium deficiency is almost always caused by incorrect pH.
Because you are using a living soil you can use a Bio pH adjuster like Biobizz pH min to bring down the pH from the feed water. This product does not harm the useful bacteria and fungi inside the living soil.
Enjoy your grow buddy!

CO2 poisoning usually will cause leaves to turn yellow quickly, and since you're only using one of those bags, I can pretty much guarantee your nowhere near CO2 poisoning levels. Those bags are next to useless, I did a bunch of test when I was looking into CO2 and having two in a tent barely raised the ambient CO2 if any. A homemade generator worked much better, and IMO that's a waste too, and much more hastle then it's worth. Save your $ don't bother buying them, it's a complete waste of money IMO. I have a C02 tank system, not using this run because of summer and would be to hard to control environment where it needs to be.

Leaves looking droopy.The leaves turned droopy when I visited the tent today. Could it be underwatering? Currently, I am watering every 48 hours 1L water until I get a slight runoff. After 2 days the soil is pretty much dried out as I got told that should be done with BioBizz nutrients.

Deformed, very thin leavesAlmost all new leaves are extremely thin on base. On some nodes only 1 finger is developed. Some new leaves curl down like claws. I suppose these leaves developed from baby leaves burned by alcohol spray week ago. But maybe it is smthg else? Should I maybe cut them off?

Brown spots on leaf tips of old growth.Hi all! Brown spots are starting to form on the old leaf tips of this young lady. I've had contradictory suggestions as to wether this is nute burn or a deficiency. Nutes were started on d12. EC has been stable at .51 (PPM 360) for the last 5 days along with PH at 5.8. Cheers.

Weird or no?Is this seedling looking weird? Some edges of the leaves are like sticking up. Then, I look to see what I thought had been a chewed on leaf. After taking a closer look though, i think it just grew in like that. All of the other seedlings are looking really good

Small white spots, and indetations on leafs, 15 days from sprout.Hey GD, im a newbie and i need some help identifying these small blemishes on the leafs of my girls.
I can't see any bugs (been looking).
Some of my suggestions:

Fluctuating RH.
Might have spilled small droplets of nute water on the leaves.
