This week is going well. Most of the growth this week has been in size rather than new nodes. #1,3 and 4 are all the same, 7 sets of nodes and between 8 and 8.5 inches tall. #2 seems to be a shorter pheno. It has 7 sets of nodes, but is only 6.25 inches tall. It is shorter and more compact. Still under T5s for another couple weeks.
Looking great... I like the structure of number 3. I also have the same mutation you are describing and amazed at the growth and structure. Already a favorite!
