  2. o yea strains are super lemon haze and agent orange
  3. Whats the distance from the light and also are you giving any nutrients yet?
  4. light is about 10 inches from plant but all the bad leaves come from the bottom and middle mostly the ones up top are good
  5. and i give it a 3 part nute every 3rd water
  6. i am thinking its a calcium issue myself, not sure though
  7. This looks like a Potassium deficiency.

    What is the Ph ???

  8. usually 6.1 to 6.5, run off is usually the same or a tad bit higher but i dont check run off that much, what can i do to help it if its a potassium problem?
  9. Feed more potassium lol :rolleyes:;).

    I recommend u feed with a nute that has a higher potassium ratio in it.

    I also recommend that u check Ph more often and make a habit of it.

    K will be taken up by the plant alot easier with a slightly higher Ph.

    Aim to keep it in the 6.5 - 6.8 range.
