Hello Dean. Just some observations and I hope I don't step on anyone else's toes as some of my advice will contradict others here
Firstly.....unless you are dosing EI then Lush Macro is not what you want unless you are also adding traces. Lush Max is the one you want Great choice of fertiliser
Onto the nitty gritty. There is no problem with using sand in a planted scape rooted or not. Not the best option if you want to maintain slopes though as it will naturally level itself from water moving across it. I use it in some tanks when I want a cheap and light coloured substrate. I don't use it in scaping tanks though due to its ability to level.
I also don't worry about anaerobic conditions in it. Thats a myth really in the planted hobby unless there are no rooted plants. In a planted tank roots will be transporting oxygen into the substrate anyway.
As for the cobbles. What's wrong with cobbles. Check out the picture at the end. This is one of my shrimp breeding tanks. It isn't scaped as such. Just arranged in a pleasing way so it doesn't look a mess in 'shrimp town'.
The tank below is an 80cm 125 ltr and has been as it looks for about 18 months. So some tips for cheapness
The substrate is playsand. £3 for a big bag. (Nearly a full bag in that tank.) = £2.50
The hardscape stones are a big bag of cobbles for £5 from B&Q (about half a bag in that tank) - £2.50
The Mopani pieces are from The range and are £1.99 each = £5.97
That is the substrate and hardscape for an aesthetically pleasing tank for £10.97
If you are wanting to scape with slopes etc then you do need a better substrate that can hold its shape better but if you are just using it to learn things and try things out then I would stick with the sand and concentrate on hardscape and plants
