all pros, no cons really, if you run the full line it has everything your plants want and need. The foliar was my favorite of all the products but its not shown since i didnt include in the feed. only calculated the feed that went to roots thru the grow, foliar is a great cal mag addition and stress combatant for if it gets too hot, the girls dont even bat an eye! amazing nutrient line up across board! follow feed schedule on their website not the bottles and you are golden! 2 week flush with finish, some of the smoothest smoken bud ive ever had and it hasnt even cured yet! this nutrient line is super clean and effective!! stinky, tastey, smooth smoke, non harsh, potent meds!

Bud B
Veg A: No need to ph never goes over 375ppm Bud B: Simple as A B = :heart: Prime: Use with mycofusion biojolt every three weeks also after flush in addition to normal feed schedule Fire: :fire::fire::fire::fire::ok_hand::skin-tone-3: Roots: Essential asf especially with autoflowers during first 4 weeks and into transition. Foliar: Use as often as you can afford. This stuff is truly liquid gold. I add in cocowet as well. Finish: Often misunderstood but totally worth it. IMO just chelates all day every day.
