looks good bro u should try and make a box for them becasue once in flowerin they can not see any light on the when the light is off. and u will need to transplant the smaller ones in the like the 3rd week or so .. but keep it up hoep all is well
It looks to me like they are streaching out a whole hell of alot. I think you should probably get those lights a whole lot closer, like maybe 3 inches from the tops.
u need those lights alot closer. the closer the light the more bushy the plant will be. if you have them to far away the plant will be tall and skinny.
yep it has been said before u need to light closer they are strechin to get light so they are going to be to top heavy u need that light closer so it can deveople better
flourals really wont i have had flourals touch them for like a day or two and didnt burn them u will be fine.. flourals can be close and if they start to change or burn u can easly move the light up one burnt leaf will not effect the plant
Are there holes in the bottom of your cup for drainage? Even if you do you need to get it out of that little cup and into a gallon pot atleast. My plants are only like 10 days old and have roots over a foot long.
Other possible cause is that the stem is so long and skinny that it is having trouble getting nutes to it's leaves. If that is the case, sorry bro but your babies are a lost cause.
Defintely get the light closer, the pot bigger and have good drainage. Also, when you transplant get some soil that has some perlite in it so that it will be less likely to rot you roots.
