Nutrient to increase bud size question

I have grown a few batch from clone and will start from seed soon cause I heard seeds better but have question about bud size. The most I ever got was about 1 3/4" x 4" and what I use for the first week in flower : Bud blood + nutrient etc… week 2-4 big bud + nutrient … and week 5-harv bloomblastic + nutrient etc…
is there a way to make it bigger?

Thank you

Have u try bud blaster?

Lights and environment make for bigger plants. Adding to many additives and such can confuse you, and not help grow a bigger yield.
