Calochortus Seedling Senescence

Giant Coreopsis

It is only mid-March but my first-year Calochortus seedlings (planted in plastic tomato flats in full sun) have mostly started to go brown at the tips. Is it time to stop watering altogether? I ask because (a) it seems early in the year and (b) my larger Chalochortuses (both second-year seedlings and mature plants) are all still growing. It is counter-intuitive that seedlings and parents in the same conditions might senesce at different times. If I keep watering, can the bulbs rot as early in the year as now?

Thanks everyone, Chris
