General organics nutes with fox farm soil

I bought fancy seeds . Used 3 gallon bags with equal parts fox farm and perlite. Feeding with G.O. nutes. Am I missing anything? Used 9-3-1 bat tea until this week now on 12/12 flowering.
Do I need to buy some PK booster or super flower stuff? I got a great light and 12 plants in a 5x5. 18" tall and in pre flower. Hoping for the 1120 grams limited by the seed bank reviews.
