As they started to flower I noticed one nasty thing, fungus gnats, so I put a bunch of sticky traps and a bit of cinnamon on top of the soil to help it dry out, this was also a wake up call for my overwatering, which might be the cause for a slight stunt.
Next time you can try to get a better light for flowering.
The plants need more lumens and a different colour (more red and orange) to get the best results.
Best of luck!
