Hi everyone!

So, i have a problem with my alocasia, monstera andosonii and my calathea! First, my Alocasia Amazonica that i bought a few weeks ago that i had to repot since it came with an ant infestation on its soil. Since then two leaves dropped and this one from the image has this giant spot on it! what it could be? Should I just cut the damaged leaf? i've been thinking about cutting the spot off the leaf, could this be effective?

And then, I have this monstera that have these spots on its leaves, that i first thought being spots due to low humidity, but now they seems to be fungal spots, because they are rounded by this yellow circle. I have a sulphur solution here that i use to treat fungal and bacterial diseases, should i use it? or you recommend other things?

In addition, there's my calathea rosy. Today i noticed this spot on its leaf and I have no idea of what this is, in fact there was another leaf that had it, but it was larger and i had to cut it off, because i was afraid of it to be a bacterial spot and then transmit this to the other leaves. The texture of the spot is kind of soft. Do you have any ideas of what i should do or about what are the problems that they have?
