I've begun low stress training this week. They all seem to be stretching pretty well. Pheno #2 is definitely faster than the other phenos with alot of pistil growth. Pheno #4 is kind of freaky, with very large stems.
I fed them this week with a cup of craft blend and some worm castings. Wish I could keep temps above 65 at night but that's not happening. Regardless, they're growing just fine.
Going to keep training them until I can't anymore. Hopefully we don't break any branches :D.
