Blackberry Auto / Northern Lights Auto

All of the plants are showing white pistils forming. We also started LST. Unfortunately I accidentally broke the main stem of one of the NLs. Luckily it wasn't a full break, so we taped it up. It's recovered well and has actually grown a bit. The yellowish/weak Blackberry greened up somewhat after giving it some CalMag and veg nutrients. The Fox Farm CalMag contains a small amount of nitrogen so it should give a little extra boost. However this plant still looks hungry. Unfortunately I mistakenly bought the hydro version of Grow Big, which has half the amount of nitrogen as the soil version, and I'm also giving half doses. I think we'll add some worm castings to improve the nitrogen levels during the flowering stretch. This is day 25 since we started germination.
