Extending a H&G schedule midway through...

In about a day I'm going to be hitting week for of an 8 week flowering on H&G. Problem I've been trying to deal with is I have 4 unknown plants in my tent running on this schedule. As far as I can tell, theres two indica dominant and two sativa dominant that were gifted to me. The person said to just follow my feed schedule for an 8 week flowering.

The problem is, of the two indicas at week four look like they're going to finish much earlier than the sativas. I'm wondering if I should continue on the normal feed schedule for the indicas, and repeat either week 3 or week 4 until around week 6 (7, or then follow the rest of the feed schedule.

So here's what week 3 looks like :
