PANICK MODE ON 2 : ISSUE LEAVES FOR QUICKPINK

I have uploaded a video for the new week, you can see "in real time" at the end Quickgreen having same issue, she is the last to have it she is a bit behind the others. Compare to her sisters Quickblue and QuickPink, the small leaves are still "up" I now not for long. When the plant is shaking it means fans are on. I really need your feed back.

Edit : i've also decided to cut the fan for now.

Thank you all for your answers. I got new pictures, it seems to be stabilized but now it is starting on quickgreen and from the border of the leaves, same leaves. Slowly but certainly. I reduced the amount of water (2L for the 3 plants despite 3) I really dont understand because the ph seems to be an issue too. I got 7.1 after giving a 5.2 ph food... I don't know how to reduce it actually.

Looks like root issues from overwatering. Could be fan burn if the plant is shaking around at that young. Happy growing and stay lit!

Soooo, I think you have fan burn. Fan is too high for that small of a plant. My 2 cents

I am following this guide : https://www.cocoforcannabis.com/how-to-grow-cannabis-seedlings-in-coco-coir/

Looks like the same issue as quickblue. It looks like a root issue here as well. Either PH is not balance or your getting some root rot from over watering. You want to let the medium dry out between watering. At this stage is when you should first start adding nuturents. So if you have been adding prior to this you might of added a bit to much and burned the root's. Usually that will show a more burnt look where this to me looks like a narcotic look that is from PH or root rot. If you have not let the roots dry out and its rot you can treat them with 5ml hydrogen peroxide(3%) and 5ml water mixed and applied directly at the base of the plant. this will kill any bacteria good and bad. Which will include your organic root juice.
