theres no way those were growing on your plants unless they are stems from a leaf that you pruned and forgot about-Or you opened up a sack of ganj above them and some stems fell out onto your buds
whats your humidity, i think there lanky shrooms coz the one in your hand at the bottom looks like one, and you say baby buds so i guess there at the bottom, were there is no light/heat to dry out buds,so mould,fungi etc . im just guessing tho.
