| Hey all, This is my first post and I was hoping to get some advice. One of my tomato sprouts has a leaf developing darkening tips that seem to be getting larger and larger. Currently these sprouts have been grown in rockwool that is suspended in hydroton clay with a circulating nutrient solution using composted seabird guano and other inorganic materials. Any idea why this might be happening? |

| It could be nothing more than a bit of injury damage to the tip of the cotyledon. Given the true leaf development they will soon begin to shrivel and die anyway. Or in soil grown plants it can indicate nitrogen burn or salt damage. In hydro growing, I can't say as it is a whole different world. But you could probably get some more accurate info over on the Hydroponics forum here. Dave |

| Awesome thanks for your feedback! A few friends I spoke to mentioned that its normal for them to die once true leaves develop :) |
