I'm going to go to a Jack's 321 nutrient setup with MKP per Greengene's video

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!

Here’s a link to Jack’s nutrient schedules, I’m not sure about the rates with MKP during flower https://www.jacksnutrients.com/growschedules-old

I’m using Jack’s 321 for my indoor grow, it’s a pretty popular nutrient brand. If you find you like it you can get it in the large bags which save alot of money per gram/lb/kilo. If you search Jack’s 321 in the search bar you should be able to find a few people using it. I don’t know anyone who is using MKP in particular but it’s very common to add a P and K boost during flower. You should definitely invest in somthing to measure E.c / ppm
