true leaves shriveling and falling

svalli · April 9, 2009

What could be the problems with my tomato plants? The true leaves are shriveling and falling off starting from the bottom leaves. Some plants have lost their cotyledons too, but many have them still on. Potato leaved plants seem to be affected worst, their leaves started to fall first. Plants have been transplanted with their jiffy pellets to 1 cup sized plastic cups, which have holes in bottoms. Soil is mixture of peat and sand (that's the only seed starting mix here). I have them under fluorescent lights by a window in a room which stays about 70°F and air humidity is about 25%. I have used seaweed, some organic fertilizer and Epsom salt when watering. Plants are getting leggy and leaves are light green and curving down (cupped?).I have now started to run a fan in the room for couple of hours every day.

Could this be disease

or environmental? I'm hoping that it is not a disease. I read about the CRUD, but this seems to be different. Could low light and too much watering and ferts cause this?

One plant is in solitary confinement after its leaves started to roll upwards. None of the other ones have shown such symptom.
