do you see problems with the plants?
depends on how strong the light is. if overkilling with DLI, then it probably had some negative effect even if not visible. if it stayed under 40ish DLI, it's probably unaffected.
For first week if i really push grow i leave lights 24/7 i want them to see sun and break soil surface fast. So ussualy by day 3-4 of sprouting i change to 18/6.
I saw way quicker development with such tactics.
So i think you only gained.
Good luck !
Check out Tentbuddy or try photone if u use apple.
They are light meters so u can see what ur DLI Is.
Hope that helps some since u got the DLI guidelines.
