No two people mix it by a book anymore. I thought like you when I came here. A sea of numbers and no one is really sharing there exact formula trust me. You will find that no two strains finish just the same.
I started with 321 which is 80% of what Jacks recommends. I grow in a conex which is limited
on space and heat is a problem in the sun and the trees I planted grow slowly. All of that and I uses a modification of Caps formula but had to change a few things because of the heat and extra silica to beef up the stalks.
If your just starting to play with the Nutrients and there numbers . I read a lot of Cap's stuff and reading seamaiden is not wasted time and you will never read them all.
I use 321 from veg to flip I use silica for better stalks I use Blackstrap because I believe seamaiden it needs to be there just a little bit. I use Cannazyme to dissolve my roots.
When I flip is a new day I back off the 321 to about 80% and add the
Moab after second week of flower
cut silica cut cannazyme add blackstrap.
I don't use cal/mag because the N it brings is just to much
I use Cal25 or Epsom salt both as foliar sprays and not together I spray as the ligts go off and the plant
absorbs it nicely. If you spray with lights on it can burn the plants Led's make magnifying glasses out of the drops.
You need air movement I have fans to the point that te leaves move around just a bit not a storm.
I run Drip to drain (out to garden) I mix my mixture and let stand 24 hours with fountain pump to keep moving
Ph is for coco 5.8 and ppms around 700 to 900 I run for 1min 30 sec three times a day. I moniter my in and out readings. In the beginning I had no idea what to do with the numbers there are folks here that can tell you what they mean.
Tempature and Humidity are very important.
Oh last thing my cost per-run is about $68 not including my electric bill
I grow in pure coco 2/3 fine 1/3 course
I flush only when needed
I flush at the end for 3days just phed ro water.
Is my way the best hell no but is still good smoke.
In my opinion the single most important thing to success is PH
All the chemistry the sales people want to you use is mostly snake oil and water.
When you start mixing chemistry then you get PH problems.
IT'S A WEED
