  2. Step one: get a ph meter. Or st least know your ph of what you're giving. It is ESSENTIAL.

    Step two: looks like she needs some nitrogen?? But I mean how many leaves are affected? If just a few, yank em and continue.

    Beautiful buds. Good vibes

  3. She started of yellowing alot like 20 leafs but as they died of now there is only a few yellow ,I gave it some nitrogen the other day so I hope it stops ,I will be getting one of Amazon rap soon since its hard to just find them around in Mexico ,thank u
  4. definitely check your PH. if you have really hard water, it can cause nutrient lockout and mimic all sorts of deficiencies. Use distilled water
  5. thank u, will do.
  6. Just old growth dying off due to getting no light. No biggie.

  7. Thanks for that ,made me feel alot better
  8. In the same mode....your N looks fine to me and distilled water can work but it lacks nutrients an generally has low oxygen. Just keep using what you re using. Like the colors.
  9. You put tobacco dust in your soil? WTF?
  10. It's tobacco leaf IDK WTF its for lol it's a mix I bought at Home Depot 50% sheep manure and 50% tobacco leaf it's says for flowering stage
