Looking for opinions on running a longer photo period over the weekend.

Stats:
26 gal
65w Coralife PC
medium to heavy planted
CO2 at approx 30ppm
EI dosing - Macros 3x/week, Micros 3X Week
N - 1/4tsp
P - 1/16tsp
K - 1/16tsp
CSM +B - 4ml solution (1 TBSP to 1 cup H20)
Flourish Iron - 2ml after 50% H20 change
Flourish - 2ml after 50% H20 change
Excel - 2ml 2X Week

Weekday lighting - On at noon off at 8:30pm (8.5Hrs)
Friday - On at Noon of at 10pm (10 Hrs)
Sat - On at 8am off at 10pm (14 hrs)
Sun - On at 8am off at 8pm (12 hrs)

The only reason for the change from weekday schedule is to allow more viewing time during the weekend.

Could I run into excessive lighting issues, algae, etc by running the lights longer a couple days a week?

Thanks,
Mike

I do this on my marine tank with macroalgae without any ill effect, although my 'extended periods' are still shorter than yours (about 12.5 hours Sat & Sun, normal 8hrs on Friday).

I do not think it'll do too much.
