New grow need help nutrients and over look

hi all
i am from California and its my first grow i am using led 450w and got some seeds zensation 75% Indica 25% Sativa this plant is 10 days old and keep in avg temp of 80f 50%humidity its 2.5" tall the soil i use is VermiSoil Potting Soil , i didn't see much improvement in the hight just in the leaves i also give her those nutrients (you can see in the picture) really really small amount.
i am worried something wrong with it if you can take a lot and tell me what you think it will be great.
thanks

looks fine. (basically) potassium helps to stretch and phosphorus bushes it. you might need to up dose you next feed but you'd have likely done that without anyone saying anything. also you can transplant to a bigger pot if you don't want to feed it liquid nutes. transplanting to a well rounded soil is an easy way to step back and let the plant do it's own thing.

Don't use the superthrive more than once or twice and only in veg. It'll prolong the flowering period
