Cloning for sex problem

[smokinjo911]

I have 8 white widow plants going right now and I decided to clone them to determine sex.

Well I took my cuttings and placed them under 16 hours of dark 8 hours of light ( I read this is a quicker method) well I have no idea what im doing wrong but its now day 18 and nothing they will not show male or female. They are however rooting very well.

Any suggestions? should I try 12/12 instead?

Thanks

Plants will not show sex until they aer sexually mature. Are the nodes alternating or opposite?

[smokinjo911]

One of the plants that I took a cutting from is showing a defined female preflower. But the cutting is not.
The plants were sprouted the last week of August.
Not sure what you mean by the nodes?

Should I take new cuttings and try them?

Thanks!!!
