Morning Guys and Girls (It is 8am in the UK) 
Ok,
I am watching my girls like a HAWK!!!
On two of them I have noticed some changes that I think should not be happening.
I think this one is caused by me overwatering? The leaves are curling down.. Am I correct?

The next, I am unsure of what the problem is.. She is starting to get little spots on some of her leaves..
I have checked for little pests and only found one or two little black bugs that I removed.. I do not think it is that although me not being too knowledgeable yet, I am probably wrong.

Is someone able to give their input please?
Kind regards,
MaG
