Week 3 Vegetative - "Sam" started off the week with 3 nodes that were tight in structure. I continued to fertigate with the same reduced nutrient recipe designed for the seedling stage. In reading up on Humic Acid (which is generally what the "Diamond Nectar" is), and how it aids in the binding and uptake of water/nutrients for the root system. With low impacts to water conductivity (salinity levels/EC), I take used the full recommended dose. I keep the CalMag down to the usual 1/2 strength as I'm currently growing in soil.
This plant still remains the taller of the twins, however the efforts seemed to be focused on stretching the existing nodes rather than adding new ones. I find this to be typical after the 3rd-5th node as the nutrients in the plants become more mobile and dispersed. I dropped the light a bit as well by this point to both reduce the stretch and because they have enough leaves to photosynthesize the extra light I find. Just my thoughts, nothing beyond anecdotal evidence.
"Sam" finished the week adding a single node totaling 4 developed nodes, and 7 inches in height.
