    You can actually do one of two things: either carefully remove the seedling from the cup for planting or simply remove the bottom and plant the entire cup, which will eventually decompose. If your seedling has not developed a strong stalk, you may want to transplant it into a larger container (using one of the methods above) and then wait until temps warm up a bit. Then locate a sunny area for planting. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/flowers/sunflower/growing-sunflowers-in-your-garden.htm

    They may not be getting enough water. Sometimes the soil of a plant can get overly dry, and it will actually start to repel water. You can correct this by submerging the pot in water until air bubbles stop coming out.

    Also make sure that there are drainage holes and that the water is able to drain away so that the plant does not develop root rot.

    The white leaves are an indication of a condition of "powdery mildew". It is a fungus that occurs on plants when the weather has been damp and the plants have remained wet too often. I would cut down on the watering and treat with fungicide, specifically aimed at powdery mildew. Neem oil is actually good. Here is more info: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

    As for the buds, leave them be. You cannot remove them and replant. You can only grow these plants from seed. The budding growths will not root.

    I'm assuming you want a chemical to spread over the entire bed that will kill the weeds but not the flowers. There isn't one. You can spot spray the weeds with and herbicide or you can do it the old fashioned way, pulling one weed at a time. Either way, you might consider mulching to keep future weeds under control.
