If you keep your car outside in our climate for any extended amount of time, there will be coolant leak, because different hose connections don't expand contract at the same rate.
My suggestion is always add a diagnostic dye at the initial charge and add lub oil. Also if you don't have a gauge or know the psi, you might need to recharge next year.. Hydrocarbon mix are more volatile than the original. That's why recharging with the original R134a if able is cheaper on the long run. Since you have mixed the coolant, the shop will have to evacuate the whole system etc.

Luckily it was not a leak. The procedure really is simple. Just need to read the directions (OK, that may be difficult for a lot of people - reading comprehension fail) and fully understand the steps before you go ahead.
