1st grow Blackberry Kush & Daiquiri Lime

I was away for a bit. When I returned, the Kush was growing nicely but Daiquiri Lime (unsuprisingly) looks quite stunted. I've been trying to figure out what's wrong but don't really have a clue. I went and bought Alg-a-mic, as I've read it helps in general to releave strees. I gave them both a foliage feed plus some very light watering (I fully watered two days before and I think it was still a bit early - I just freaked out a bit when they were droopy, but they were just going to sleep). So I just split like 0.3l between the two of the Alg-a-mic to give them some goodness. It seems Daiquiri Lime picked up some speed since the Alg-a-mic treatment! We'll see. She's still way behind... We're having some cold and cloudy weather now, so I'm not expecting miracles really. Also, I came to check them today and... are those pistils on the BlackBerry Kush? Is it starting to flower already on day 22?? Not sure that's good?
