Yes. I do notice a difference with the SC actually doing what it is advertised to do... Feed the herd! I don't think it's MANDATORY however I do think it's worth using it and I will continue to do so. The Bud Explosion... Yes absolutely crucial to your yield and final product. For what everyone is saying the MC lacks... The MC along with the BE as soon as pistils hit are an incredible combo. I'm sure one could use just the MC and then BE soon as pistils pop and be very successful... If you HAD to pick just two...
This line is so affordable tho... My goodness! There's no reason to not use all three. I think they have a real winner! I love how I don't have to use Cal/Mag anymore.
So we'll see in another 2 & 3 months how these autos and photos turn out! I absolutely think the half your base and double your bloom booster 15 days til flush/water only is key here.
