The plant size, especially in autos, are determined by the rootball mass. There are a lot of factors but small pots make small plants period and 1.5 gallons is a waste if you ask me. I would never do less than 3 gallon and even then it will be a small plant. I typically only go under 5 gallons when intentionally trying to do a fast small plant. Autos should never be run under 5 gallons for decent yield and I typically use 7.
That said if you run too hot of soil it will flower right away and be a small plant Regardless.
In a 1.5 gallon pot it will be root bound fast and start blooming early and be small... but that may be desired?
I try typically to either not repot by using the final pot for the seed or only repot once. Last time I was low on space and repotted twice and the 3 gallon pot I used in the middle was full of roots before I could believe it. But I got it out in time to prevent early bloom. Some autos are so fast you really need to go big right away.
Ah ... roger that. Yes, you can start with some bottled nutes when they are big enough. How far along are those beans?
I would start with 1/2 the recommended dosage. And with autos, you might want to stick with 1/2 the recommended dosage for the duration. Which organic nutes are you using?

5 gal minimum! I might go up to 7gal next time. Trust me. I just made that mistake, put one in a smaller pot and it used up all the nutes only 3 weeks into flower. Now I'm playing catch up and I know it killed my final yield.
