Should I get some cal/mag+

  1. Hey,

    After about 2 months, I think I'm ready to give my pc case growbox another try. I tried it once, but they failed miserably due to bad soil and bad lighting. Now, I have it ready for SWC hydro. Before all I had was 42 W 2700k, this has been upgraded to a 105 W 5000K. I am using Pure Blend Pro Grow and Pure Blend Pro Bloom for nutrients. I have heard that Pure Blend Pro is lacking the calcium and magnesium, so I need some of that cal/mag+? I've also heard that cal/mag+ has quite the N, so you think it might burn? Also, what is the use of Hydroguard I'm seeing so many growers use? Thanks! :wave:
