yellow leaves on seedlings need help

hi everyone i am a new grower and would like some advice. i have 10 feminised easy sativa seedlings. i sprouted them and used the sun to start them growing, they stretched out for the sun so i put them under 4x 18 watts cool white florescent lights (65.1 lumens/watt). i have noticed for a week or more that they have not grwon much and that the new leaves on top some have turned yellow. i would like your adive on what is causing the slow growth and yellowing leaves. i am in an asian country so finding the 30-30-30 fert. is almost impossible and have not yet added any fertilizer to the soil. i will put some photos in this thread so you can see what i am talking about. any advice would be appriciated very much thanks in advance

i think they have been this way for ever a week
thanks

Well if they stretched out for the sun, putting them under floros isnt going to do a thing but accelerate the condition.

I dont think the new leaves are too yellow. Many new leaf sets are lighter in color.

Sativas almost always are more stretchy.

I would put it back out in the sun quickly.

Good Luck.

thanks should i be concerned at all about the slow growth, a buddy said that they are growing slow because they are building big roots??
what does anyone think
thanks

If they seem healthy I wouldnt trip.

those look a week old +? Probably started germinating on the 31 April give or take a day?

I would guess they are a couple of weeks old.

I think you need sun. That may be an outdoor only strain.

Rooting is an ongoing process, but it shouldnt shut down growth on top. If it has stopped growing, back outside it needs to go.

my window is on the west side of my apt is it ok if they get direct light only at that time

the strain is feminised easy sativa

Looks to be pretty healthy, but where did u get your soil, it looks pretty shitty, but maybe its just the pic.
