Help with VERY Early Sexing

This is my first grow so I'm just looking for some noob info.

Set Up: 3 Gallon homemade aeroponic, 400 watt MH about 2 1/2 feet above plant. FoxFarm vegging nutes, lights 20/4

My plant is about 8 inches tall and looking very healthy and bushy (i believe). I ordered Early Widow seeds from advanced seeds and was told they would flower automatically by now and are supposed to be finished by 8 weeks. I believe that the preflowers are finally just beginning to show at 4 weeks now. I also have alternating nodes along almost the entire main stems.

I dont care at all whether it is an Auto or not, I kind of hope they gave me regular feminized seeds for the hopes of higher yield, but i was wondering if i should switch to 12/12 soon to initiate flowering. I know the plant will get much larger during flowering and I am afraid if i wait too long i will not have the space required for a mature plant.


**How much longer before preflowers appear behind Stipules???

I have actually changed lighting period to 24/0 for hopes of increased growth.

I know Auto's do not require a change of light period for flowering to begin, but how/when can i be sure this even is an autoflower. I have read about many people not receiving actual autos, but just fem seeds. Which, if this is that case, I would need to induce flowering by changing light schedule


PLEASE REPLY THIS NOOB NEEDS HELP

in my experiences, the males show themselves early and obviously. if not male, then female.
