How to prepare your R/O water for nutrients in coco.
I presently use Flora Nova. I like it better than the modified Lukas Formula for coco. However, when I do deep water culture, then I use the lukas formula with Micro and Bloom.
I water every day with full nutes every time I water. The only time I cut my nutes in half is when the plant is still very young.

Some side notes that might not be mentioned in the video.
I know people might get confused as to why I only use Flora Nova Bloom for watering. I do so because it has all the nitrogen, etc that a vegging plant needs. I get better results with this than if I use Flora Nova Grow during vegging. When I use the three part system by General Hydroponics, I only use Micro and Bloom. See below.
I sometimes use General Hydroponics, Micro and Bloom, a modified Lukas formula. When I do that, I use 6mL of micro per gallons of R/O water and 9mL of bloom per gallons of water. I also use 1mL of calmag plus per gallon of water. However, if I am using city water or well water, which I do not recommend, then I don't use any calmag plus or very little, like 2mL per 5 gallons of water.
The basic breakdown I use in the video for Flora Nova Bloom. I only use Bloom for veg and flower.
1. I shoot for 900-1200ppm for plants with a fully developed root system, i.e. a plant that has at least filled up a 1 gallon container with roots. Before that I use around 500ppm, from seedling on up.
For almost 5 gallons of water, i.e. a 5 gallon bucket almost filled to the top, 5mL calmag plus, 6.5 teaspoons of Flora Nova Bloom = about 1000-1100 ppm. If using R/O water, then 8mL of General Hydroponics PH up, should bring you to 5.8 PH, which is what I shoot for. This gives me nice and healthy plants. Super green. No deficiencies.
If you are using city water or well water, or anything other than R/O water, you will need to adjust a bit. First, you will not need much or any calmag plus, as calmag is in both well water and city water. Only use 2mL per gallon of water of calmag plus for city or well water. You will need little to no PH up. Check ph after adding calmag and Flora Nova Bloom.
