  1. at 2 weeks im thinking of introducing blood meal, good idea? bad idea? any other recommendations?
  2. Blood meal is great for adding nitrogen but is not a full-spectrum fertilizer. I recommend looking to some other fertilizer(s) as your main food and supplement with blood meal. Careful with it, you can burn your plants.

    You definitely don't want to use blood meal beyond the veg stage.

    There also is a bit of controversy around blood meal possibly causing mad cow disease years later (not from smoking weed grown with it but handling it as a fertilizer).
