Mainlining almost complete. It is for 3 of 4, but decided to let the 4th grow out an extra node before the 3rd and final topping. I'm learning that once the babies reach this stage of development with a thick sturdy stem, they are really very resilient to bending and topping/lolipopping etc.
I realize that the mainlining technique adds several extra weeks to the grow - I hope that all that concentrated growing power makes the difference and we end up with 32 abundant colas!!
