Not sure what fertilizer you are using, but I would look at amount you are giving the plants. If it is a hydroponic situation or a more convential situation. Traditionaly I never fertilize plants more than a couple times a year for a root system, and give them a organic leaf drench every couple weeks so they can soak up through transpiration. Hydroponics uses a solution that handles nutrients on a flush system. I do not do hydroponics, but daily for regular fertilization is way too much I think.

Are you using an organic fertilizer or a chemical fertilizer? Are you growing in pots or in the ground? Either way, every day is WAY WAY WAY too much. Over fertilizing with a chemical fertilizer would show some signs like yellowing burnt tips among other things. How green are they? If they are an unusually dark green, excess nitrogen is likely the problem. Stop fertilizing.

Not having humidity in a greenhouse is uncommon. Usually you have to do extra stuff to reduce humidity.

I don't fertilize tomatoes. Ever. I make a good soil and condition it without fertilizing.

Your temperature range looks OK, so I would stop with the fertilizers and slow soak each plant with water.

You don't say if this is containers or in-ground so specific recommendations are hard to make.
