Northern lights auto

So far everything is okay. They needed nutrients sooner than I have then. All the photo plants needed uppotted. They were showing signs of zinc/mag Def. I started using the mars hydro UR45 for a couple hours a day. Trying to just keep them healthy. The tall one is closest to the light and I tried some super cropping or is it monster cropping. I forget . I just bent the tips down some . Raised light a little. Started feeding Foop flower nutrients. They seem a little stressed and light yellowish. This hasn't been a perfect grow for me.
