So i must have skimmed through this thread b4 and some reason never replied. Probably just stoned.
Anyways i have spent alot of time researching different ppm totals of each element in a lot of different brands.
A good youtube channel i will add a link to explains in detail much better than i could here.
That being said he was using a jacks blend or masterblend just tweaked a little.
I then tweaked that a little and have a formula you could run from veg all the way through to harvest. With only a small addition of monopotassium phosphate (MKP) during peak flower but that is a discussion on its own.
I made this up similar to jacks at 4:2 following Greengenes Garden in youtube. I have been using it until plants get into their big pots then i have just been using up old nutes that were given to me.
