I'm going to go to a Jack's 321 nutrient setup with MKP per Greengene's video.
But I was wondering.........is there was a feed chart somewhere....?
Do I use the same amounts of nutrient throughout the grow?
When to add MKP?
....geez ...how can a person tell if his or her plant is low on calcium...or magnesium?....or K?
How can you tell if your plant is hungry?............. does it's stomach growl?
thanks for your help!

I’ll also be adding MPK this run, any chance you have a link to buy it off Amazon?
