Just a quick question, surely someone knows. I have an old 1k hps digital ballast (energy station). I have a gavita e series 240v power cord… Will i have any problems using this cord for the ballast?

Have a close look at the power cord, specifically look for indented lettering.
It will probably reference a UL number and a wire gauge something like “…14AWG”. That indicates the capacity of the conductors.
The heavier the conductors the lower the copper losses. This is most important if you are using 120VAC instead of 230VAC to power the ballast (half the voltage = double the current)
Assuming worst case (120VAC), allowing 10% for ballast efficiency you need about 1100Watts or 9.2amps. Assuming a 10’ power cord length I would want 14 gauge wiring (12 gauge would be slightly better).

It’s 15awg. 240v. It’s for the gavita e series with ferrite rings for noise reduction. The ballast supports 120 and 240v. .

That will work.
Personally I’d use it, but replace it with a heavier gauge cord when convenient as the copper losses will be about (my estimate) 0.75VAC or 7 watts.
The ferrite is nice as that will clobber common mode noise.
