When to upgrade my first troop?

I've recently start my Clash of Clans again (I made the mistake of upgrading TH too quickly), and was wondering when to start upgrading my troops.

I'm currently only on town hall 3, the lowest you can be to upgrade troops. All my collectors are maxed for this level, as too are my defenses aside from walls. Nearly all I have left to do at this TH level is to upgrade troops, but I'm wondering should I hold off or upgrade now.

It costs 50k to upgrade any troop at the start, and that's the most I can hold in my storage right now (I haven't built the second storage's cause I don't need them yet).

I was just basically wondering, should I start upgrading my troops at this TH level, or should I wait till I'm at a higher TH level?

Yes, keep your lab upgrading all the time. Try have no down time on your lab keep t pumping them upgrades constantly, at your th level getting level 2 archers and barb plus gobs is needed once you upgrade th justm kae sure you keep lab going

Upgrading your troops in lab should always be your number 1 priority.
