Pachira Aquatica slowly degrading
I have a similar problem with my pachira, altough i have yet to find a solution. I also suffer from the yellowin-brownin-falling leaves, and i've been searching the web for answers. I had many, some of them contraditory, so i am kind of lost. First i thought it was lack of water. I used to water it every 15 days, because the vendor told me it required little water. Then they told me it requires more water than that, so i watered a little more, and even bought a humidity sensor rod (those you stick in the dirt) in order to check how much water was around the plant. Found out it was not lack of water so, i started to be careful about my watering - not too much, not too little. Then searching again in the web, they told me it could be too much sun - or too little. The vendor told me the plant was supposed to be in half-shade, and it is - near a big window but without too much direct sunlight. Then i thought i had to change the vase, because it was little, so i thought the roots couldn't support the plant anylonger, so i changed the vase to a bigger one. Then i found this site and i read about the mites - found none. Another evidence as you can see in the photos is the little drops of gooey substance you see under the leaves - i still don't know if it's normal or is it a sign of something. So here i am not knowing what to do next. My pachira keeps degrading day by day, but still sprouting new leaves despite the ones falling. Any help is welcome.
Thank you all
