I haven't grown for 10 years, and will now be growing in a shed in the high desert. Using organic like before. The only thing that has changed is I will be using LED full spectrum lights.
Looking for suggestions and grow techniques

What is the environment like in the "Shed"? Size light? Shed?

LEDs run cooler, but seeing as you're in the desert this is more a positive than a negative.
LEDs also increase the demand for Mg on cannabis as well so anticipate that ahead of time.

Other things -- be on the lookout for light burn, which often mimics Mg deficiency and K deficiency in patterns on the leaf. When you see mobile nutrient deficiencies on upper leaves and not lower ones, it's light burn.

Find a good PPFD map for your light. Knowing the hot spots can go a long way in avoiding light burn.
