how often do you water and does that containner have drain holes looks like maybe overwatered or how old is it it might need some nutes if its been in that soil for a while it could have used up any nutes alos what kinda soil you using?
i keep mine on the floor, its prob. your soil just dont over water the nutes are released with water just give it what it needs until it gets bigger and uses up some nutes then you can give it a good flush
how old r they ffof has enough food for 3 wks to a month and to me it looks like the soil is a little hot for them already hence the twisting and stuff just let them ride it out i had 1 do the same thind topped itself and everthing i just didnt give any nutes for awhile and it pulled through...
im in 2 gallon bags and im keeping them they say it is i gallon for every foot tall you want to grow but others believe this is nonsense i grew a foot tall plant in a dixie cup
