Hey
@pop22, I am having the same learning with the version 2.0 of MC. I had some major clawing when trying to use it at proportions I had used MCv1.0 at successfully. So I went back to the drawing board and did some testing. I use RO water by the gallon jug, and it comes in at 7-9ppm before adding anything to it. I then add 2.0 grams of MCv2.0, 1.5 grams of Sweet Candy, and .5 grams of Bud Explosion to get to ~500-515ppm. I then use ph sup to get to 6-5-6.8 ph, usually around 6 drops.
Plants have looked much better. I did have to do 2 flushes over three days before starting with the updated formula. The only thing I haven't accounted for is CalMag. I use GH CaliMagic, but decided against using it until I see signs of deficiency. Not sure what 1ml, 2ml, or 3ml will add to the ppm. I will probably drop the Sweet Candy to 1 grams to keep the ppm of the mixture near 500ppm. Just thought I would share my findings in case it helps.
