    I use neem oil for pests like this. It is safe for people and pets as well as friendly insects that don't eat your plants and can be used on an organic garden. Here is more information:

    As long as the stems are still green, they should be fine. The use of an electric trimmer shouldn't make much of a difference, unless they actually damaged the plant with choppy cuts (not smooth). These plants can normally be pruned back by a third to half their growth.

    You might want to add some phosphorus to the soil to help with blooming. Bone meal is a good source for this, or use a fertilizer that has a higher phosphorus ratio.

    Try giving the plants some bone meal. They may be lacking phosphorous, which a plant needs in order to bloom.

    There are a number of things that could be causing the yellow spots on the leaves, from pests to fungus. It could also be suffering from shock, as it's still rather newly planted. I would treat the plant with neem oil, which is an effective, organic pesticide and fungicide. Also, check the soil around your plants to see if it's staying too moist. If so, allow it to dry some. A soil test may be helpful as well in case there is something missing, which can then be remedied once you know the nutrients it needs.
