Blueberry Kush auto - 1st grow [harvest]

I got my first look at the explosive growth of cannabis plants. really amazing how much they change over a couple days. She seems to be really happy with the situation I'm providing. her 3rd set was a 5 finger and the 4th looks like it will be a 7. lush green tip to tip and satisfying growth. lost about 12 hours of light due to some thunderstorms but we're still good. I'm looking to up the feed a little to see how she responds. also am trying to prepare for the challenge of this as it isn't considered an easy grow. gh ph kit must be doing the right thing for me. ec/tds meter and ph pen on the way. I'm liking how thicc the stem is getting, makes me anxious to start roping her up but week 3 and 4 will decide how I go about lst. she's been looking quite purple in the stems so I hope that I popped a really expressive bean plus my night temps at like 68°f-70°f should help. all in all, an easy breezy week of growth
