Toast

I'm going on 2 weeks with a new whole wheat starter... first 6 days were 75 starter/100 flour/125 water.  Changed at day 7 to 2 feedings of 20/100/100.  But the last 5 days or so it's become very sluggish, and although it doubles (8-10 hours) it doesn't collapse (photos are at 12 hours).  It doesn't have much smell, is very stiff, and doesn't show any liquid.  Is it time to change the feeding ratio?  thanks!
