I dont really understand your ppm thing but that's me and not you. I think part of is that you don't use CalMag....minus some ppms numbers there.....and if you don't use LK and Sweet you can minus some ppms there as well......my actual nutes for blooming are 500ppm Cal Mag and 800 Pro Bloom so my ACTUAL BLOOM NUTES are at about 800 through the whole blooming part of the grow. The rest is CalMag and supplements so

Regardless Dab ppms DO matter. I threw in some photos here to show my point.

Pic one is a strain called Brainstorm. This plant was fed a total nute solution
of 1350ppms through late flower (that includes CalMag and supplements) and her final yield was 6.85 oz. (I don't use C02 btw just fyi)

The second photo is two plants I'm growing now. The one on the left (with the yardstick) is the same strain....Brainstorm. Same seeds, same bucket, same lighting. There is one difference between her and the first one.
She is getting a nute solution of 1550 instead of 1350. Her final yield will be almost DOUBLE FOR THAT ONE REASON ALONE.

PPMS MATTER!

PS....also tossed in a few root photos of a plant that grew very successfully (Master Kush......yield was around 6 oz) but this is what the roots looked like when all was said and done. NO ROOT ROT......thank you Cannazym.
