Hey man im new to this so im speaking only from my own experience... First off what kind of lights do you have? im guessing some kind of HID... if yes i can attribute this slow growth to the nutes (dont think youre supposed to use this much until youve seen a few nodes at least). Also this pot this seedling in is huge... So the plant might be developing alot of roots instead of developing growth as well... for next time i would use a party cup first and transpant.just to give you a picture to compare with here is one of my plants after less than 2 weeks (i use 250w dual spec hps)
For now i would just wait on the little guy probably he will take a while to veg. and go easy on the nutes man
They look fine. I like to transplant into pots that are only slightly bigger than the ones that they're leaving. I notice that the surface is quite dry, but watering evenly is tricky when the plant is too small to drain soggy soil. Bottom water though, and they'll be great. Just nitpicking!
you shouldnt use nutes that early man. just an advice
i did it, and the first two leaves just twisted and got yellow. buuuurned.
they still look like shit too. cant save leaves from a bad burn
