Hello all,

I made some pear crosses last year and I am currently growing the seedlings 
under grow lights.  Most of the seedlings are beginning to suffer; symptoms 
are as follows:  The leaves starting from the tip are turning black, and 
eventually moves back to cover the entire leaf.  In others, the stem turns 
black and in time evelopes the seedling.  I have been removing all dead 
seedlings and cutting off blackend leaf material.  Does anyone have an idea 
what this problem is and how to prevent it?

Thanks for your help,
