  1. please help what does this mean?
  2. How long has it been growing?

    It's probably a nitrogen deficiency, most likely due to Ph lockout. Flush your soil with ph adjusted water.
  3. do you mean i need all new fresh soil?
  4. bump need info
  5. No, I mean you need to test the run-off of your water to check to see if it's in the right Ph range (6.3-6.8 for soil). If it's not, you're going to have to flush your soil or water a LOT with ph adjusted water. Then your plant will be able to take in the nutes it needs.

    Don't add any nutrients until your Ph problem is fixed.

    Assuming it's a ph problem. Pics would really help diagnose the problem.
  6. it is the tap from my house has a very high ph i have water the plant with a lot of 6.5 water, how much should i put through the soil?
