Hcf controller and turboprop captain reported possibly losing separation when a turbojet on approach overtook the turboprop and entered IMC. The turboprop aircraft was no longer able to maintain visual separation and requested a 360 turn for spacing.

Narrative:
Aircraft X was on a visual approach following aircraft Y. Aircraft X asked for a three sixty degree turn for spacing because aircraft Y went into a cloud and aircraft X lost sight of the preceding aircraft. I instructed aircraft X to turn left heading 180 for spacing. I had less than 3 miles between the aircraft. Aircraft Y was on approach 030 descending. I'm not positive the aircraft lost separation but they may have.the aircraft X pilot did not sound confident in his requests. I should have been more positive in my control of the situation. I should have been suspicious of the weather and aircraft X's ability to follow aircraft Y when the aircraft Y pilot reported being IMC. Sector 2 is an oceanic sector that also deals with oceanic non radar separation as well as approach control. Recently it seems the radar assist has been combined during the day when it probably should not be. It may be a staffing issue.
