yes only the bottom ones

Dont worry its natural for the bottom ones to go yellow and die, do not remove them from the plant wait untill they fall off then throw them out, the plants are using the goodness from those leaves and thats why they are turning yellow its nature.

btw i used some root inducing powder yesterday,

I dont know about that i reckon you only use root powder once and thats when you first take the clones from the mother plant.
Take care not to over or underwater them and you should be OK.:hippy::stoned:
