Bloom Boosters past 2 weeks?

I am beginning week 10 of what was said to be a 9-11 week strain. I had fed the plants assuming a 10 week schedule. But now beginning week 10 they are not ready to start flushing, 11 weeks is looking about right.

Should I just keep running the "ripen" mix using the dry koolbloom for another week or is that going to have a negative impact on the buds? Is it OK to run 3 weeks of dry booster?

I ask because I've been told the dry mix is powerful and to be careful with it, and everyone says to only run it during the last 2 weeks.

How do they look? Growing in dirt I assume? If yes then just stay on schedule to it as a two week flush is good too. You can tell alot by the leaves on whats left in the plant flush time.

No, it's hydro. I am going to have to go an extra week on the powerful dry powder koolbloom mix. Is it OK to go 3 weeks on that instead of 2 weeks?
