Actually Im worried because I find few seeds. Im in 8 week of flowering and all my pistils turn brown week 4-5 but I drench plants few times with essence to prevent bud rot and also spray boost on buds so I thinking burn pistils is from foliar spray. Anyway crop is ruined.I agree with tessarecting. Looks like a normal "embryo" seed that is still waiting to be pollinated - no need to worry.
