How did you come to the conclusion it is better than whey? Whey protein isolate is a very good source that is rich in the right amino acids. However there a lot of different vendors that use different processes to refine it which does affect the quality.

If you want super cheap whey buy the unflavored bags on the net. Basically the raw ingredient before they add the flavours and stuff. I get mine in 10kg bags for 180 dollars.

Sweet lupin flour has a low amount of leucine. Leucine is the amino that helps your body absorb and utilize the protein. So if you want to go that route I would suggest buying some leucine and mixing it with the flour. You can find vendors easily on the internet. I myself get L-leucine 500grams for 24 dollars. Which lasts forever because you are only using 2-4 grams at a time.

If you can't find that you could get some BCAA's which include it.

Seems like you have had quite good growth. Congrats.

Plant protein is always better, healthier for the body than animal protein. Especially for women. I was in the preliminary stage of breast cancer and since I eliminated animal protein from my diet everything bad from inside my boobs disappeared (last mammography some weeks ago). Read the "China Study". I can't say this often enough: READ THE "CHINA STUDY", People.
