I upgraded my elixir storage to 5 at first, too. But you will want to take it all the way to lvl 11 for the second PEKKA upgrade. And, once you hit storage lvl 8, which holds 250 000 elixir, raids will be able to loot it for the max amount (67k with three storages) so you might as well take it all the way to lvl 11. personally, i've been swimming in elixir -- i've not farmed for it all and have been focusing on farming gold, yet i've always been able to keep up with my lab upgrades.
