Guano and Palm Tree Ashes

I was under the impression that bat guano was very high in Nitrogen. Not great for flowering. Palm ash sounds interesting as will give a carbon boost to the plants. Either way will work. A top dressing will release the nutrients slower than making a solution the day before. That would allow the nutrient to infuse the liquid, therefore a faster delivery. Well, thats how it works in my head...I could be wrong. good luck and happy growing
