Reddit mentions of Marijuana Horticulture: The Indoor/Outdoor Medical Grower's Bible

Honestly, the best thing you can do at this point is to get a decent grow book. I recommend Marijuana Horticulture by Jorge Cervantes. The ebook is $10. He's been writing and rewriting this thing for 30 years, and it can take you from your first grow up to production of top shelf bud.

How much homework have you guys done on growing? If all you know about so far is tents, keep reading! Read the sidebar resources, read the grower's bible and maybe a couple other books like it. Once you know enough that you believe you can put together a complete shopping list (there's some shopping lists in the sidebar for reference), then come back and ask for critiques.

Once you're ready I would say start small, like one plant each, and take them through the entire cycle. That will give you an idea of what you'll be getting yourself into when you go full-scale.

I strongly recommend reading these two books:

• The Cannabis Grow Bible - Green (if you're only going to read one book, read this one. It's the best book on growing by a wide margin.)

• Marijuana Grower's Handbook - Rosenthal

  There are another couple books that I've read which have good bits of information but are by no means necessary to read. They are definitely lower quality than the two mentioned above:
  
  
• Marijuana Horticulture - Cervantes

• Master Gardener's Medical Cannabis Secrets - Moon

It's likely not a magnesium deficiency because a magnesium deficiency would cause chlorosis all over the plant and not just the leaf edges (outside of hydrogen, oxygen and carbon, chlorophyll has 4 nitrogen molecules and one magnesium molecule).

Micro nutrient deficiencies can be a pain to diagnose but empirically speaking this will clear up most any micro nutrient deficiency you'll likely encounter including copper:

I'd like to caution that growweedeasy is not a very reliable source of information. I've found way too many mistakes particularly in plant lighting (there's essentially a lot of what appears copy/paste going on). If this were a case of copper deficiency due to pH lock up as mentioned in that website then you'd also likely have iron (some new growth would be turning yellow), manganese, zinc and boron deficiencies from too high of a pH. This is a better source of information:

by jorge cervantes, covers literally everything, many things you wouldn't even think of (at least i wouldn't have), and helped us grow an amazingly healthy plant before we had to get rid of it :( . i'm sure you could find a pdf of it if you don't want to pay for it, but it really is the grower's bible
