I have grown using just about every method over the years. I've tried all of the popular nutrient lines at least once.
I've made all of the mistakes and learned along the way. What I have come to realize based off of my experiences is that simpler is better. There is nothing simpler than 100% coco and blumats. I'm on my fourth grow with this method and everything is going great. The first three were some of the best grows I've ever had and they were the easiest ones ever. It works great with coco because it uses calcium nitrate for the nitrogen source so throw that bottle of calmag away you won't need it. The only thing I add to that is fulvic acid during veg and epsom salts in flower. You're going to need a PH pen because PH is extremely important.
VitaGrow maintains that PH without any wild swings. These are the nutrients I use and I use them according to the instructions except for diluting it for new clones and young seedlings. I also start reducing towards the end of flower so that when I harvest I am at 1/4 strength or less. You'll need a reservoir to hold your nutrient solution. I just use an 18 gallon tote and run the line through one of the bottom vents on the tent. I also have a small pond pump on the bottom to keep the solution moving and aerated. The plant on the left is a cross I made of Strawberry Kush and Ketama. The tall gal in the middle is a Pakistani Chitral Kush. Back right that you can't really see is a Night Nurse and the front right is a Black Domina that went in a week after the rest due to some issues I had following a PH issue from using a bad PH pen. No spots, blotches, yellowing leaves, curling tips, etc. I can buy enough VitaGrow to last a year for what some people pay for one bottle of an additive. Fulvic acid is extremely inexpensive if you buy a pound of it in water soluble powder form. Tank is 3 feet off the ground and I usually keep about 10 gallons in it. There is plenty of gravity pressure to keep things moving. You don't need a dozen or more bottles of stuff to grow good weed. Do you keep the reservoir outside the tent for space reasons? Is it a sensor that detects if water is needed, and then releases it? I just had a discussion with @Dynamo626 aboit needing to water coco everyday, which it appears this system does. Looks like the reservoir can, or should be changed every week, right? Do you keep the reservoir outside the tent for space reasons?

Looks like the reservoir can, or should be changed every week, right? There is no contamination from organic matter to cause problems. The coco is dry on the top but wet below the surface. Actually the blumats were putting out too much water.
I had to move things around and pulled them out without putting them into water so they started releasing water. I have been using VitaGrow for years and I have no plans to use anything else. VitaGrow is basically the same chemical salts used in all the other nutrient lines and supplements.
