Lucas Additive

[Scottyboycx]

i'm running hempys and an autopot on lucas and i am looking to branch out a bit and buy an additive. But the problem is theres so many its like mind bogglin. I'm looking for something to help up my yields a little . I'm on a budget so these at 300£ per tub are no good.

pk13/14 look nice is it good? any suggestions?
