My plant is dyingโฆ I donโt know if itโs getting too much ...

15โ pot with drainage

Last watered 6 months ago
Itโs cactus soil and I try to only water it when it gets dryโฆ but in the intense heat/sun now Iโve been watering a bit moreโฆ Ihave moved it to a spot that gets a bit less of the afternoon sun to see if that helps . It also had a bout of scale about a month ago so I treated it with insecticide and then some nutrientsโฆ I think it may still have a bit of scale
@SillyPlantGirl thank you so muchโฆ it does have a drainage holeโฆ I added perlite also. Iโm new to this app so didnโt complete the details properly sorry!
@SillyPlantGirl thanks! Me toooooo
