Too much or too little?

OK, it's been about a week now since I have repotted with better potting mix with about 10% perlite. No nutes yet. My plants seem to be able grow nice new growth but the under growth is pretty much dying and dropping off.

The ph of the soil is 6.8.
No nutes.

It's been a week, I'm assuming I have fixed the initial fault, have I waited long enough to see a healthy plant yet?
Bear in mind I dont have the super powers of an indoor lighting system.

Does anyone recognise this sort of sikly leaf?

I have slighty pulled the plants down for I have limited room outside.

O, I forgot, I had a very minor case of thrips ( little bugs in Australia ) I have sprayed them once with a organic dose of water, a little olive oil with some garlic. This made the leaves too shiny for my liking as if the oil could clog the leaves, I havent and shant do this again.

careful you don't over water.... looks good
