Do i need to put my plants into bloom?

You could put them in bloom. They’re some small pots to keep them going until the end so the sooner you flip to 12-12 the better so that it doesn’t get too root bound. If you do this method again I highly suggest using fabric pots. They out perform plastic all day long. In plastic pots the roots find the edge of the pot and keep wrapping itself around and around until it’s root bound. In fabric pots when the roots find air they automatically prune themselves off right there and find somewhere else to make roots. I’ve also done some side my side comparison and the plants in fabric pots are twice the size of the one in a plastic one. Good luck the rest of your grow. All your plants are beautifully green!!
