I use Masterblend, Calnit and mag. Like some of you, I was getting sick of all the bottles and added crap that did nothing but cost me money.
I use the 2.4grams MB, 2.4grams calnit and 1.2grams mag /per gallon.
In flower I add more mag and leave everything else the same. Plus I add a pk boost.

All my plants get this feed. From seedling to harvest. Its a little hot for seedlings but they power through it fine.

Yeah buddy. I'm liking it so far. Using a 5050 mix of Greenleaf bud booster and mkp. Gonna flush with Greenleaf's sweet, just bc I have it and I want to try it. I have a feeling that I'll eventually just settle out on calnit+Mg+mb+mkp. I usually add kelp too. Sometimes fish in veg.

That was my original recipe but toned it back a little as not all plants tolerated it well. 2.0 MasterBlend/2.0 Calcium Nitrate/1.0 Magnesium Sulfate per gallon and it works great. No burning at all, beautiful color and healthy roots. I also add .5gr BioAG TM-7 and that just rounds things off with some micro nutrients. Have had no issues with algae, run a little H202, like 10ml/per gallon food grade if any ever presents itself.

Have used it for pepper, tomatoes (the bane of the gardener's world) and just about every other veggie with this stuff. Simple and it works.

What do you use as your PK booster?

Anyone have any experience using masterblend's 4-18-38 mixed with calcium nitrate 15.5-0-0 and magnesium sulfate in hydroponics? I always like to run my nutes on the low side. When I was using GH's three part on my last grow I was running around 700 to 800 ppm's in both veg and flower and the plants seemed to be happy. But now switching to the masterblend my plants in veg seem to be good around 300 ppm's. I'm actually afraid to go much higher as the plants are already showing nice dark green leaves.
Thank's for any info?

Any issues with heavy metals in Masterblend? Is it as clean as Jacks 5-12-26 or Megacrop?

At least they promise - "Masterblend is 100% soluble in water because we process all of our ingredients to remove plant & animal ingredients, any insoluble non-nutrient matter, and heavy metals."
