Thanks for the reply, Haze!! So you def. think it's a K def?

Is it just because she's hungry, or could the K be locked out due to my possibly low soil pH? I need an accurate way to test soil pH... any suggestions on doing this without the help of a pH pen or something? I've done the waiting 30 min. after watering, and ran a little distilled water over the top and tested that runoff.. but it seems I'm just getting the pH of the water I ran thru (6.0), and i'm sure that's not totally correct.

Will watering with molasses help the def., or do I need to use something more/stronger?
