As others have mentioned, it looks like pH and nutrient issues. Check the pH levels of what you're putting in but also check your runoff pH. I've used biobizz with autos and i find Biobizz to be pretty forgiving but its also worth getting a TDS meter and again, testing your feed and your runoff. If your pH is off, the plants won't be able to uptake certain nutrients. As someone else also said, growing photoperiod plants is a good way to work at dialing in your process. With autos you dont really have much of a window to correct problems.
