Update, time-lapse video

Just a quick update, things got a little out of control when I decided to replace the 2 part nutrient I was using with what I thought to be a 1 part nutrient, FloraGro. Big mistake, several plants started to turn yellow and further investigation was pointing to lack of nitrogen.
Then found the FloraGro is a 3 part nutrient which required two other parts, FloraMicro and FloraBloom to provide correct nutrients N-P-K as well as micro nutrients like Calcium, Magnesium, Iron and several others.
I think the issue was reverted in time and plants seems to be moving on from this scary event, here's a 10 day time lapse, one photo/day.
