Normaly the first leaves, and some of the fan leaves die off as the plant gets bigger, because it concentrates is energy to the top, where the cola is so it'll be ready for flowering. Are probably should start ferting, but remember to keep it minimal for now, and increase it as you go, very slowly. Dont shock the plant.

Good luck
LIP Reviewed by LIP on . Stop me before I kill again! ...Part two :D I need some serious help. The bottom leaves of my 3 week old plants are turning yellow, drying up and dying. I used to water every other day, then every third day, now every fourth day. What do you think it is? I haven't fertilized them yet. I have them 2" away from two 100w cfls. I killed my first batch with too much fert. Should I fert now????:( Please help !! Why is this so difficult??? Rating: 5
