New grower : Amnesia zkitlez Auto

I'm using light:mars hydro fc 3000 evo Mars hydro inline fan exhaust Tent: 1x1x2m Biobizz light mix 20% perlite 19L fabric pot

Light is now 55% and 50cm Veg was 35-40% diming

Humidity range Seedling was in Humidity dome 75-80% veg 65-75% max with good airflow Early flower 55-60%

Temperature was from 24.5-26max

I'm on week 3 early flower Do I need to feed more? Isn't it small? What I did wrong?

What i can improve? Thank y'all
