Purple Urkle Clones

I was given a couple of plants that were already 4 weeks into veg. They are supposed to be "Purple Urkle" strain. They were in 1 gallon pots (Miracle Grow soil) when I got them. I transplanted them into 7 gallon pots with pro-mix and put them in my tent on Sunday (10/25). No issues and the plants don't seem stressed at all. This year I have a new 3x3 tent to replace the 2x2 tent from last year's grow. I'm not planning on any training and plan to see what happens. Since these are indica strain, I expect them to fill out rather than up but so far, they are just getting taller it seems. I will let these stay in veg cycle for a couple weeks and if they do fill out, I'll switch them to flower.
