Young quick seems to have issues

🤔🧐 I will investigate more about it, thank you very much for your answer !!!

A seed has all the nutrients they need for the first 10-14 days. I run a DWC. no soil/coco. Just water. I only have them sit in water with zero nutrients with an air stone for the first 10 days of there life when they have started the third node I start feeding.The first pic in week 1 of my "TopTao" diary is around when they start to need nuturents. Since you have already fed her and she is over fed I recommended to hold off a bit longer. You can just cut back on the nutrients and she will be fine. Just slightly stunted until she gets bigger and can handle the nutrients you are feeding. Yes BeautifulCraftRreddit is correct. not all plants can handle the same. Its always better to have an underfed plant then an overfed plant. Happy Growing

Small edit : I just did a video where you can see her sister QuickGreen Growing x3 fast speed mode (with good music) 4 minutes video...

Yes, but others are fine. Quickblue was the first to raise from ground, she seems special. Maybe Beautiful is right. Thank you all of you ♥️☺️♥️ I will wait a bit more other answers and I will select the winner !!! At Chow_13 : I raise them in Coco, I know I have to feed them from day one, my substract is fertile.

She is to young to handle any nutrients. So she is suffering from nutrient burn. Only use PHed Water until the 3rd set of "True" leaves start to come out and are the size of the bigger leaves on your current pictures. And at that point go very very light on the feeding. Happy Growing

Personally I say soil is rich in Nutrients so might be to much for the seedling but should be fine anyway. Them leaves don't actually matter
