It actually raises PH, and in some "rare" cases PH has been way too low anyway, it could indeed help. But as for providing calcium in a nutrient solution, I'd still rate it as a fluke. Unfortunately there is a lot of misconception in this field, that is actually a result of cherry picking (or call it purely circumstantial observation). In some cases personal observations of any kind may be very useful, in some others they are falsely applied as a general role for something else

PS: still be careful when using calcium nitrate, as it may provide unwanted nitrogen (and induce too high vegetative growth for tomato). Best is to include it in a formula or use a product that is based on calcium nitrate and providing sufficiently Ca.
