Hey seasoned growers, how accurate are preflowers in determining the plants sex? I've got what I think is a male because each node has one spike and a ball, but my plant is still under 24/hrs of light. The thing is I can't see anything on the rest of the plants so I'm wondering if it's an accurate way to tell. These are all bag seed as well. It's about a month and a half old.
It should be very noticeable once you have around 7-9 nodes on the plant The ball/spike is not going to determine it for you easily so just let it get bigger an wait for a very rose petel like shape with a tiny hair creeping out of the top If you got that you've got a girl if it's a knobbly ball with no hair you can assume the plants either a late bloomer a hermie or just flat out a bollock filled male Also if you have problems getting a good close up look you can try to use the mag's smaller bubble over a digi cam lense to catch it on a monitor blown up 2:1 Hope that helps
