Hello again everyone, I came to the subreddit last time and everyone was so kind to help me. I’m going on three weeks or so now, but recently my starter has been a little sluggish in the past couple of days. I don’t know how to explain my current situation,  but it does rise, but not as much as it used to. 

I had been feeding 1:1:1 for a week, then moved onto 1:2:2 which worked fine for a couple of days, but yesterday it seemed to rise, but not quite double anymore. So I switched to 1:3:3 because it seemed like it was rising and falling at a very quick pace. So I gathered some photos of its current state. 

I fed at 4:30 and now it’s been 7 hrs, but I’m still not able to tell whether it has reached its peak or falling or should give it more time to possibly rise to at least double? 

Please advise I don’t won’t to give up.

TLDR  
\- My starter is going on 3 weeks   
\-1:1:1 worked, moved to 1:2:2, worked but rose quickly   
\- I moved to 1:3:3 just today, it’s been 7hrs and it hasn’t doubled, but getting pretty close  
\- I’m not sure if it’s peaked, or grew as much as it could. 

\- Should I wait a few hours longer for it to double or is this past proof and I should feed?  I’m sorry I’m not even sure what they mean by dome  
Or going flat because it’s past peak. 

Thank you all I hope to hear from you again 

Not quite ready to give up, but a bit frustrated
