I think it would be a good idea to move the cage away from the window but I’m not sure what else to say. Hopefully some other members could suggest if anything is wrong
How hot does it get where you live one thing I noticed is the cage is next to the window so the sun may be coming through and overheating the cage so your Cham might be looking for a cool place to hide and get cover
It seems like your Cham is trying to get out of his enclosure and they usually do this when there is something wrong with it. Can you attach more photos so we can see if there is anything wrong with the enclosure.
Please believe the members on this forum, a lot of them are very knowledgeable and they want the best for your chameleon. Also get rid of the coil uvb and get a linear bulb ASAP.
Is that a rope hammock in the back?
If so I would suggest taking it out as I’ve seen chams that have gotten their claws stuck between the rope and they've been ripped out.
Im not really sure if they could be affected by eating the plants, I personally think it would be fine but if you want to be on the safe side either buy from somewhere that don’t use fertilisers or wait a few weeks for the fertilisers to come out of the plant like the person at the greenhouse...
