bro it looks like the brain is dying, the very top where the growth is, it looks like its dying so if you want to clone it to keep it, since you dont have branching yet it dont look like, cut the top like an inch from the top, chop that off, and clone the plant, theres many ways to clone it, i like 420fied's cloner, its an aero, it sprays the bottom of the clones constantly and they root out, or you could get some rooting hormone or rooting gel and dip the stem in it and put it in perlite or soil and water it, if you use rooting powder and perlite or soil, make a resivior with a bowl or something, use a solo cup as a container or a foam cup and cut holes all in the bottom of it, and put it in that bowl with an inch or two of water and the clone will suck the water up from the bottom instead of watering it from the top and rinsing the powder off. just research ways to clone, if you clone it, it will be like the same plant exatcly in terms of genetics and stuff, but wont have the rooting problem that this one has, but if you do this, you might wanna think about vegging alittle longer, the clone would be like a young plant. needs some time to plant its feet and grow a bit
