Noob, opinion and fertilizer...

Hi all , hope i dont get flamed, first grow so just dont know where to post my doubt.
Well I got a Auto BH growing under 45w 6.4k lumen cfl and 3 inch height.
Does it look healthy?
I need to know how to dilute my 7-7-7 fertilizer for my 10 day plant...and how much to feed...Thanks loads

your leaf edges are curling up is there a tray under that planter if so make sure you empty it after each watering ,it may also be from salt build up in the soil. at ten days its too soon to be adding nutes give it more time

Dont fertilize until the plant is much bigger, or you will kill it.

I would wait until you have at least a plant and one month of vegetative growth in that pot, then fertilize while you are looking for a bigger more comfy pot or whatever.

if yr in potting soil no ferts for 5 weeks, plenty already in it.

Well I was told a 3 litre pot will be enought since it was a Short Stuff variety which doesnt exceed 15-17 inches bit confused now. Thanks for all your advice guys
