Bad growth in the first 2-3 weeks. Why?

Thank you all for your response. I also think its a genetic problem. unfortunally i cant upload more photos in this threat but you can see my better Banana Blaze in my grow report. The seeds were in the same batch (DutchPassion).

Depends on the breeder, some seeds grow bigger and some doesn't grow much at all. On one grow, I had three big plants and three tiny runts. But these were first genration experimental cross. Don't waste time and space with tiny. Toss it out and grow another one. Nothing to learn from the impossibly small.

Double check the PH and PPM. I like a noooob didn’t buff my Coco before planting and was watering with RO water which doesn’t have any nutrients the plants needed so the stopped growing completely. I got impatient and pulled the plant but I wish I kept it a while longer. Your plant looks good still so maybe it is just genetics. I will check your levels and if those are good then I’d just hurry up and wait. Good luck hope it grows for you!
