Greetings RIU!
I’m presently 7 days into my first Coco Coir grow, and really my first grow (had to scrap the first and address some issues 3 weeks in).
I’ve been researching non-stop, and I have settled on doing the h3ad formula (6M/9B) using GH nutes. I had a couple of questions...
I’ve done extensive planning and research about NER, ppm, EC, etc. I understand and am comfortable with the ppm of each specific nutrient, and have learned how to figure out specific ppm by using the specific gravity and guaranteed analysis info. Now, for the question...
According to all of the information I’ve seen, cannabis requires more nutrients after the first two weeks of growth. My present formulation (including using 2.5 mL of calmag) is giving me roughly 111 ppm (222 EC) of N, 60 of P, around 110 of K, 100 Ca, 50 of Mg (these are rough numbers from memory). I am presently feeding at around 450 EC (225 ppm) of diluted nutrient solution. As the plants grow and get into the vegetative state, the nutrient requirements increase. For example, I’ve seen the required Nitrogen range in mid veg around 200-250. How do I reach this target, when my full strength solution (6M:9B) is only like 550ppm? Do I increase the amount proportionally (like to 12/1? Do I leave it at 6/9 and add other things?
Anyone who could give me a definitive answer that’s experienced both with coco and growing, I’d appreciate your input. One of the problems I’m encountering as it comes to researching this stuff is the wide variations in technique among growers on forums, coupled with ample amounts of Bro science. Would love input from some more experienced growers.
