Timer error

Just checked my tent and light was on 5 hour into dark period, one 15 minute segment was left on. This has probably been like this for 2 weeks,plant is 5 weeks in flower.
Seems to be bulking up nicely but have never grown strain before pineapple express. Anyone guess likely consequences of this, couple more week flowering.

Not familiar with the strain. When I've intentionally reverted plants to vegetative under 0-hours of darkness, it takes over a month. The first few leaves that begin to grow from sugar leaves around the bud elongate and twist a bit. It's pretty obvious.
