star pupil bag seeds for first grow!

Hi all,
I'm Angel from the UK.
I started my first ever grow, 3 weeks ago. Basically, a friend got a cheap deal on an oz of star pupil, cos it was seedy as hell.
I tried to germinate some seeds and they popped their little taproots really quickly. At this point I was like shiiiit, cos I didn't expect them to sprout, so wasn't prepared at all.
Anyway, a few weeks later with some hastily scrambled together kit, the babies seem to be doing really well.
They are in a DR60 tent with 2x 150w leds and a smallish filter n fan. I've planted them in coco coir/ perlite mix, and I am feeding them canna coco, they have just had their first feed. Temp is 23c and humidity just over 50%.
Any advice would be gratefully received cos I am a total newbie and I am winging it, I'm not gonna lie

Why was seedy?? Does person who sold you that seeds haved hermi in grow or there was intention to made
more seeds thru another generation??

This questions will save you if you know answer...as sometimes seeds come from hermaphrodites so you will
not loose precious time on growing more seedy buds in future..
