april 21st is spring, but i dont think there were long days then which is why it was budding after you set them out. june 21st is the longest day of the yr where we live, so i would guess that since the days are getting longer now it is starting to reveg right now. i would harvest, and leave the bottom bit to continue vegging and then later in the summer bud again, at the normal time. i didnt notice the leaves, but im glad stinky did. if it is reveging, and i think it is, your bud will continue to get more and more leafy the longer you leave it out.
