Pf Tek getting no yield

Pictures are of first flushes of first and second tub, i did pf tek to S2B, Put 2 pint jars in each tub. im not sure what im doing wrong but im getting barely anything. Up until now ive always done broke boi tek but I bought a pressure cooker so this time I did PF Tek. With Broke Boi each tub would always give me over an ounce, now each tub is giving me like 10 single mushrooms at best. Any ideas? I feel kind of lost now with the growing stuff, Not having a pressure cooker before I was sort of forced to do Broke Boi. Now there are so so so many options that it makes me crazy to even think about. What is a relatively simple tek I can use to get a large yield using a pressure cooker?
