Tips of leaves turning yellow

  1. I was using the grow flouros, and I have heard on here not to use them. I went out today and bought some regular flouros, I have 2 4' fixtures with 1 sunshine bulb and 1 daylight bulb in each. 6500K and 5000K. When i was changiong my lights out, i noticed that the tips of 2 plants are turing yellow. What am I doing wrong and how can i fix it. Thanks guys.
  2. im pretty sure that it could be soil or ph lvl but maybe someone more experienced can help because that does not sound like a light problem
  3. Sounds like Phosphourus deficency. Do you have a pic? I have this also and am working to fix it.
  4. I can try to get one tonight wehn i get home, What can I do to fix this. I am gonna get a ph tester today so I can keep an eye on the soil and everything.
  5. Post some pics. From your description, nute burn, not deficiency, is a prime suspect.
