1st Grow, try to get to harvest

Have a new addition in place of the glueberry that died out early on. I work at a grow and was tasked with killing off a couple hundred plants due to there not being enough room for them yet. Clones had been taken from all of the plants and will have many more than what we killed off. I asked and was able to snag a plant before it got shredded. Found out that the NL from 00seeds is not an auto flower, I had sworn I had bought 2 auto flower collections but one turned out to be photos. As for the Seedsman plant I triple checked the order and the package and both say auto. Only 2 explanations, either the seeds got mixed up before being packaged or the seed I planted took on the photo trait instead of the auto trait. I have 2 seeds left so will plant another later down the line and see if it turns out o be an auto. Noticing some yellowing in the leaves, I am going to switch up the fertilizer I am using and see if that helps. Plants might be a little too short to start using the trellising but using the string to tie down the branches wasn't working great. Even though the growth has been really slow, still pretty happy over all with how they look.
