Thank you for responding to my post
Oh I didn't realise about the bottom soil - I guess that makes sense, thank you for letting me know.
I read that I should re pot after a few years and if the roots had grown through his drainage holes and given how sad he looked I thought that might be why.
I don't think I kept a lot of his original soil, mostly it is his new soil. I was worried his old soil was causing him to be sick thinking that he might have a fungal infection and just because of how old it was. But I've since read it's better to keep them with some of their old soil to prevent shock.
Do you think that's what is could be? He seemed fine for 1-1.5 weeks after re potting, so I thought he was ok.
I have changed his watering routine a few times trying to understand what he likes best.
For a long time I was watering him twice per week, 1-2 cups of water. I checked his top inch of soil and it always felt dry when I watered him.
But then I got worried about over watering and changed it to once per week, 1-2 cups (I mist him a few times a week as well).
Now I am just really confused about what to do, I'm terrified of over watering and underwatering.
He is right near a very big window - It's a big sliding door so he gets quite a bit of light. It has just turned to winter here and there hasn't been much sun the past week or so though. I did move him about 2 meters to the right of where he was, closer to the door so he could get more fresh air thinking that might be the problem as well.
Thanks again for your help- I really appreciate it
