I'm growing tomato plants under a high pressure sodium light. They are about
a month old, very healthy looking, and have just started to bloom. Despite
looking healthy much of the new branches are becoming very tiwsted and are
curling downwards. The leaves are fine, although the plants have some of the
biggest leaves I have ever seem on a tomato plant. I've heard that large
leaves has something to do with the plant being cold, as they are growing in
my basement. Could the twisted branches also be due to the cold or might it
be something else?
