yellow leafs with purple edges

you cant see it so well, yet i have notice the leafs are yellowing and on the edges its purple.

any help?

to hot and looks like your feeding too much.
what is you light sced?
do you have a fan.?.
how ofter are you feeding?.
what are your temps?.

i had one that i gave a buddy and a few weeks later i looked like this. he is using the soft whit cfl's i figured thats what made it look like that. i tryed to save her but the top just wilted over. good luck with finding the problem

i had it on a 24 hour light and brought it down to a 16/8.
and i was giving it big bloom like ever watering.
i am so sad.
i think also it was cause i had it in a small pot for a long time so that would contribute to it being over fed.

i kinda wanna just start all over yet i dont wanna give up on them cause they are females i feel like i should just put them on a 12/12 and get them over with.

im trying to clone my fuckup. it was a very pretty short bushy plant so i said fuck it lets start over with its kid. pluse i cant fuckup no worese with this plant
