The plants seem to be doing very well. They are growing very nicely in width. I reduced the fertilizer a bit because there were a few small fertilizer spots on one or two leaves.
At the beginning of the week I stripped them of a lot of leaves, it seems to have done them good, they are now in even better shape than before.
I will probably switch to 12/12 lighting at the end of next week or the beginning of the following week and start flowering.
