Without knowing how you took clippings, from which part of the plant you took them from, and what you put them in, it is hard to determine the issue.

One thing you should know is that you do NOT want to give clones too much harsh light because they are not trying to grow new foliage growth, they are trying to establish new roots.

But really, 5 days is a very tight time schedule to expect new growth from fresh clippings. You will not get new growth from clippings from ANY plant (in my experience) in just 5 days.

Hope this helped,
