I finally got my nutrients and stared to use them ...

I wouldn't use any nutes at this point. There's enough nutrients in soil to make your lady to stand tall. Keep the light close but keep a close eye on your temp. Good luck

Yes the leaves are still little but the plant itself is little at that very moment , don't worry she will thrive correctly thanks to the feeding and the leaves will get bigger. However if the leaves remains little when she will start to grow correctly then it will be a phenotype variation ( a genetic trait ) wait and see 😊👍

if you put the light closer the temperature and light's intensity will increase and the plant will grow faster, try halving the distance but check every day or even twice a day to see if the plant has grown and if you need to move the lights up. hope this helps ! 🚀
