By now you will have seen that those are new growths . Hope you have lifted the bulbs above the level of the media,if not you still have time, so do it now!!
They're not new growths, they're spikes---all but two of them. They're currently developing their buds but the sheath-like aspect of the spike has opened and now all the 12+ buds on each spike are starting to emerge.
So like, 6 spikes in total, 4 on one plant and 2 on the other.
