Starter Rising too quickly

My starter was in the fridge for 2 weeks while I was away, and since doing 2-3 1:1:1 feeds over the past week it's rising very fast, sometimes tripling in 4 hours.  My main concern with this is accumulating so much discard, but I'm also curious if a slower rising starter is better.  Would a 1:2:2 feed slow things down as it would need to eat more?
I would guess the temp in my Brooklyn home is a humid 72-80 degrees most days recently.  

Thanks for any help!
