  • Hey I seen your post about Cal mag being required with LED grows.

    I have a LED grow and I will be using Advanced Nutrients 3 part system (Micro, grow, bloom) and Advanced Nutrients say not to mix with other nutrients like General Hydroponics.

    Should I be fine with using just this 3 part system I'm going to be using. I have never read about Cal mag with LED so now I'm worried where I do t have it and it will take a month to arrive if I order.

    You can use other products on top of the 3 part system. I use home soil mixes which help with calcium. You can use any product you desire. I recommend cal mag+. It's an advanced nutrient product, however any product is just as good. Don't believe all advanced nutrients sayings lol. General hydroponics or general organics profits can be used as well.
