My Starter isn't Growing!

Toast

As of 4/30, my starter is 5 days old. On the second day, I fed it 100g of whole wheat flour and it quadrupled the size in 12 hours. On the second feeding of that day, I fed it with 50g of starter and fed it 50g of bread flour and 50g of whole wheat flour and 100g of water. So basically a 1:2:2 ratio. Ever since I've fed it half bread flour and half wheat, after 12 hours, it only grew about 5mm above the rubber band. I'm reading all these posts and some are telling me to feed it more or feed it less.

Should I be feeding it at a different ratio?

Should I feed it twice a day even when it doesn't grow too much?

Should I let it grow for a full 24 hours and then feed it? 

Should I stick to 100g of whole wheat instead of 50g of bread flour ad 50g of whole wheat?

1st attempt at this

Started with 1/2 cup all purpose flour and water it sat for 2days now feeding twice a day. I have hooch on top daily?  I am discarding 1/2 cup daily feeding adding 1/2 cup flour & water (considering weighing). I am on day 7, no growth a few bubbles nothing but hooch between feedings @12 hours.
