Probiotic Supersoil Autoflower grow

I am having a nutrient problem and I believe it is a CA MG issue and then addtional bloom nutrients are needed for one of the soils. I am using two batches of soil to compare a local batch of living supersoil, which so faR has exceeded my expectations. I have avoided liquid nutrients as much as possible but with the nute deficiency I wanted to correct this as fast as possible since it is an autoflower. I am considering picking up Vegamatrix line up to finish off the Flower. I did so some heavy low stress training to spread the colas apart to get more light further down. I did not top any of the autoflowers, I have always been against it since I feel like I am running against the clock and want as little stress as possible. My cover crop is crazy to deal with and not sure if I can do anything to keep the crazy growth from going through my canopy. If I do not keep up with it it mixes within the branches and I came close to cutting off a few branches when trimming the cover crop.
