Deficit/The lack of

Looks like you need to bump up the cal mag a bit and possibly run less water cycles (looking a bit droopy). The cal mag will likely also have Nitrogen which will be good to bump up a bit more if you are going to continue more weeks of veg. I would also double check the PH to make sure its maintaining 5.9 and not affecting your existing nutrients and uptake. Looking like a great setup though!
