Latest pics from the shed.....

[HARDDON]

They won't show sex until either a) if you grow inside you cut your lights back to a 12/12 cycle and wait a week or two, or b) if you grow outside -- somehow recreate that or wait for the end of summer.

Some plants will have pre flowers long before the light cycles have been adjusted.

However, you will have to look on the MAIN STEM at the node JUST ABOVE THE FAN LEAVES.

Your pics for sex determination need to focus on the secondary growth points. That is where preflowers will emerge....sometimes.
