first week grow, help?

this is a low budget stealth grow, im using two 75w CFL's one red and another blue spectrum, and i have a couple more 35w aroud them.
im trying to grow 4 seeds all feminized; one big buddah blue cheese, big buddh cheese, big buddah silver cheese and a barneyfarm lsd. ive had these seeds on 12/12 from seed, i gave them maybe 3days 18/6. i wnt a personal stash nothing big. thses have been about a week each from first sprouting from soil, from the 4th of this month. what do you think are they too small for there age?.. i got really small room vertically in the room. i done the 12/12 for it to stay short any more tips and advice please thanks. id say i have just over a meter hight to work from.
today i feed them some baby bio herb thing half the strength, my friend uses it and it really does good with it. how tall you think they will get?
thanks

Real tall.

dude your talking 4+ months if you want to grow them properly. No serious grower will commend you for trying to grow with just cfls. The plants, put simply, will not get enough light and get very tall. Many factors in a grow make a the difference and light is one of the top contributors. Sorry to tell you, invest in a good light (600w or 1000w) in the meantime learn the basics (The Growers Bible by George Cervantes is highly recommended).
