First time grow, wondering if every thing looks good or not??

hey guys,

My first grow is white widow (as i've read after probably not the best choice), the leafs are kinda going white, is this a good thing, i don't know? :S, i keep them in my conservatory and move them out doors on nice days, they've been growing for like 3 weeks now and don't know if they are the right size or not??

there is also these yellow crustaceans appearing on one plant, i removed them and it has been fine since, any ideas on what it was?

3 weeks they aint good for 3 weeks is that 3 weeks after the pooped through soil or 3 weeks all together and what light are they getting.and what medium are they in pall temp humidity

looks like not enough light or well to far away..

Post your setup to help diagnose why your plants are small for the age.

pretty sure it aint suppost to turn white till flowering, might wanna look into that

I didn't think they looked all that great, I'm a complete novice btw, haven't spent hardly any money on it at-all, like seriously just went out bought some seeds from my local hemp shop and planted them up, haven't got any lights other than the sun, using a watering can to water them and (don't laugh) miracle grow as a fertilizer ,, what fertilizer do you recommend i buy, brand and everything so i can just go buy it?
