Full sun only if either grown in full sun or acclaimed.

Your plant, if it came from a nursery, was grown under a shade cloth and never exposed to full sun.

Give it open shade outside, or full sun through a window inside (full sun shining though a window is filtered and is not direct sun).

The terms direct sun and full sun are not interchangeable. Direct sun can be for any length of time. Full sun indicates a spot where there is direct sun for 6 or more hours. Unless you have a sunroom or south-facing bow/bay window, there is no full sun inside. Being as close as possible to your sunniest window is where Scheff would prefer to be, but will tolerate less exposure. If taken outside, any exposure to direct sun should be introduced very gradually to avoid sunburning your plant. Starting with the first or last hour of the day should be safe.

Any search, on google or elsewhere, returns information from a wide variety of sources. Some may be more accurate than others. Consider the source of information, not just the fact that it came up in a search result.

I think it is sulking from its change of location, and the droop is not due to wind IMO. Stick a skewer in the soil and test for moisture. Give it a good drink if it needs it (and hose off the foliage) and temporarily stake that branch. The plant should finish its pouting in a couple weeks, and it will hold itself up on its own.

From the pic the soil looks dry. After the 3 in 1 did you rinse off the remainder that was left? Possibly he needs a drink
