yellow areas and leafs gone

Ok this is my first time growing and have a problem that I am not sure of.

I have a planat that is about 2 months old and growing outside. It has really been doing good except for a coupel of things,
1. There are sometimes white spots on the leaves, only one here and there.
2 a yellow kinda patch turns up on some leaves.
3. A couple of leaves look like something has eaten them, leaving holes or parts of the leaves gone.

At first I thought it may be bugs so I made a mixture of Garlic and sprayed them, seem to help at first but it has now returned, all the symptoms.

They are watered by rain water collected and nothing else, also the get a little rapid grow every now and then.

Ant help would be appreciated
