Before we get to the numbers... First off, you say you're feeding 1 Tablespoon per foot of plant height? The instructions I see for these products say .5 to 1 teaspoon, not Tablespoon. Perhaps you just quoted the wrong unit of measure. I'm making the computations based on 1 teaspoon. Next, Green Planet states in their product brochures that these products are meant for coco or soil-less. Frankly I don't see how that's possible because they don't contain most of the micros (ie iron, magnesium, copper, etc). It's not really a complete nutrient system. Lastly, you'll note that one of the ingredients in each product is Potassium Sulfate, yet there is no Sulfur listed in the guaranteed analysis. The Sulfur component of Potassium Sulfate is 34% of the amount of Potassium so I accounted for it in my calcs. Boost has a second source of Potassium and I'm not certain as to how much of each product is used in Boost. Therefore I assumed half the Potassium came from each source.
On with the show...
This is what things look like when you feed the Grow fertilizer
I typically look for 150-175 ppm N. The Green Planet grow is 211. As long as you're not seeing tip burn you're OK.
Next lets look at what happens when you change to the Bloom fertilizer.
The N drops to 105, which could lead to yellowing plants. P goes up a little, and K jumps to 175. I like to see K in the area of 180-220 ppm so that's close.
What happens when you add Boost to the Bloom?
The N stays the same since there is no N component in the Boost. Still lower than the 150ish I'd like to see. P jumps to 119. I've run as low as 20 ppm of P with no problems. 40-50 is more than adequate. Over 100 and I've seen P start to lock out other micro nutrients, so 119 is a bit concerning. K is almost 280ppm. That's approaching the upper limits. I've seen catastrophic results when K gets over 300 ppm.
With the products on hand, lets look at another alternative. Feeding 3/4 teaspoon Grow, and 1/2 teaspoon of Boost for the blooming phase of your plants.
N raises to 158 ppm which should keep them green. P drops 26 points to reduce the chances of excess P locking out micro nutrients. K is 170 ppm which should be adequate. its only 5 ppm different than when you feed the Bloom fertilizer with no other supplements. If you're gonna change anything, I'd consider the Grow + Boost fertilizer program.
