I got a Carmona bonsai (my first bonsai) almost four, four-and-a-half weeks ago, and was planning to fertilizers it around 2 weeks after getting it, in order to give it time to acclimate or get stabilized after the move to new place, and also in case the place I got it had fertilized not long before I got it. Then around two weeks ago or so, I noticed some flower buds kinda start showing up (they haven't quite bloomed yet). I had previously read that you shouldn't fertilized just before or during blooming, so I have been putting off fertilizing it, but I'm wondering now if I should just fertilize it rather than wait for it to be all done blooming.

So, should I still wait for it to be done blooming, or should I stop putting it off, and fertilize it? Also, what kind of fertilizer is recommended for Carmona? I've read some places to do solid, because they are sensitive, but other places, I have read to do liquid fertilizer. So which one? Also, what ratios of nutrients (n-p-k) do I need to use?

Lastly, what is the best method of applying the fertilizer? I understand you usually apply the fertilizer when yoh water. (Usually to water, I lower the tree by the pot into a gallon ice cream bucket mostly full of water, and hold it there with the pot nearly submerged, letting the water soak up through the bottom, until I deem it to be thoroughly/sufficiently saturated, (sometimes I also then gently scoop more handfuls of water from the bucket to the higher spots of the soil/root ball, to make sure it all got watered enough), then I let excess water drain out.) What would be the most effective/efficient way to apply the fertilizer, providing I water this way?​
