Looks like the beginning of a call mag deficiency. Just grab a bottle of calmag or powder form and add to your feed.

Minor discoloration on seedlings (nitrogen toxicity?)
If anyone has advice on the middle plant, I'd hugely appreciate it. I added nutrients last Thursday (7 days ago) and I am pretty sure it was way too early. The middle plant has some discoloration on the leaves. Will avoid any more nutes until I transplant into 5 gallon smartpots.

Yellow tips on the leaves
Hi guys. Why did the plants start showing yellow ends (brown dots at some ends) on the leaves? I use advanced nutrients sensi coco A+B 2.5ml/l + B-52 2ml/l (770ppm) and tap water. Run-off 720ppm, ph 7.0 (as far as i know i don't need to care about ph with ph perfect fertilizers).

C02 exhaust bag
Hi. I wanted to know if adding a CO2 exhaust bag in a small grow tent (60x60cm) is effective for overall growth? I'm European and most off my pairs said it was useless but the topics dated from 2010s and I couldn't find current definitive argument so... here I am.

I read around that a plant if sent into bloom and then when it was re-planted it could have lower yields ... but only if it continues to grow with a small leaf ... like this plant .. which has been growing for 1 month with only a leaf with 1 tip .... now it is returning to 3 ..5 -7 ... I wait until a good size and we are there ?? .. or do you think it is not to be cultivated and is it to be thrown away? will have lost power? or this is similar to a moster cropping .... technique which consists in cutting cuttings from a mother plant just entered into bloom? is similar ? no ?

Light markings on new leaves.
I'm on day 9 from putting the seed into a paper towel. Day 7 from putting it in soil. Day 5/6 from seedling sprouting. Looking closely there are markings on the leaves, what are they and should I be worried? Is the little girl stressed? Also is developing slowly?

Does anyone have an idea what is happening to this plant? The lower leaves looked like calcium deficiency so I gave her cal/mag. Now the upper leaves are looking bad. Is this light burn or a deficiency?
