Whats up with my plants. Big and early pre flowers and single leafs?

First of all I have 5 plants that have at least four tops a piece. Everything was going very good and then they started looking like they are going into flowering in mid june. Very strange. Then I started to notice massive amounts of trichomes forming every where ( even on the stems) and the new growth was 1 leaf shoots. What's up? They look very healthy, are very stinky and the four main tops are getting thick. They wont go into flowering until about mid august so whats up with the super frost, single leaves and massive looking pre flowers? Sorry I can't figure out how to upload pics

No there fims that I started them in the middle of march inside for 2 months and put them out for the season about mid May. Tahoe og, critical hog, cum lauda, giga bud, og #18.

Thanxs for help with the pics. The #2 picture is about 1/2 of one of the top main cola's. 4 cola's per plant. plus I topped side branches. I hope to have some monsters by the time they are done.
