There's about 4-6 preflowers.
Most of the stipules are very sharp pointed, and crossed, and most of the nodes are even. (wives tale signs that it's female)
Some nodes are uneven (growing out if the stem at different heights)
When I look at the preflowers they're kind of a banana/pear shape. Not spade shaped. But not one has a pistil yet.
I transitioned from 24/0 to 12/12 over a 6 day period, and a couple days into the transition I noticed the first preflower showing.
I guess it's too soon to tell still. The seed broke ground mid April.
