hi arctic high!
First and foremost,good choice on the EQ.I smoked an incantation of early Girl a few summers back;all around good smoke.
The pre-flowering stages under long daylengths usually begins and pronounces the plants around the sixth/seventh week of active growth.(around the two month mark of the grow alltogether)
Go to the middle of the plant.The bottom of the plant where the older growth is located is undergoing"petrification"at that time in order to fulfill it's anchoring duties.The top of the plant's growth is young,tender and in full on development mode(no hanky-panky yet,,,it's still too young there).That's why,the fourth/fifth/sixth node in the middle of the plant is most appropriate to look.They develop there first.(It all depends on variety and climate)
Choose a big leaf .Follow it's stem(the leaf's stem/petiole) back to the main stem.(meristem)There at the "node"/branch union,you should find a newly forming rosette that promises to become a branch later on.Between the three will be a growing dot.
How that dot plays out over the course of a few days will tell you wether it's a staminate or a fruiting plant.(a pollen or seed bearing/male or female plant.)
Female pre-flowers take a bit longer to become obvious than males.They don't have much tension to them,it looks like it lops away from stem and leaf stem,sorta curling off to the side.It'll split open and two white styles should grow out.The female pre-flower is nice and lush green. The calyx looks like a green teardrop
Male pre-flowers hold tension and come out sorta upright.They look like a ball with a spike on the end of it.They don't have as nice of a green color as female pre-flowers do.They'll only look like a bunch of bananas when the plant is nearing it's most floriferous point.
Judging by the pics,if you're gonna keep them under long daylenghts it could be another week/two weeks before you get to see how obvious they make themselves!
Good call on the transplant!Mj likes to have plenty of room for her wandering feet
If you need some help with that,provide pictures of what you find;I'm sure you can find someone here who'd be more than happy to tell you what they see!
hope I could be a bit of help
