My Toms in the growbags have pretty much stopped growing, with the
bottom leaves turning pale. I gave them a feed of Tomorite yesterday,
hopefully this will pick them up.
My bush Toms in pots aren't doing great either. :-(

Tomorite will not help tomatoes which are doing poorly. The problem
could be either over-watering, poor drainage or insufficient light.
