I'm sure the company knows what they are doing,it looks like 9-4-11 npk combined , plants are mostly selective and will take what they need as long as it's there. The fert co wants you to succeed and make it easy to keep you,they do mix it weak so you buy more and reduce chance of burn ,a seasoned grower will use 3 part or make their own from salts and adjust according to plant needs. I would mix it as they recommend and if you find in bloom they are too green just use b. Some soils have an analysis printed,alkaline soils usually have plenty of calciumGood day everybody,
im gonna upload some pictures from the nutrient-solution i use right now. Its a 2-component mineral fertilizer, claims to have knowledge and science and so. Made for soil. I dont know much about fertilizers, ive just realized 2 things about the product that confuse me, 1st is, they always recommend to use bottle A and B, both with same amount, from beginning to late flower. Now bottle A holds the N, so i expected this one to be reduced in flower. No, they recommend 4.5-5 ml of both, A an B in late flower. Thats a lot of N.
Second thing is, it does contain lots of calcium. Bottle A has twice as much Calcium as Nitrogen. Means, if you mix 5ml/l of Bottle A, you dont only get 400mg/l (or ppm) Nitrogen, but also 800ppm Calcium. Ive seen some recommendations that were only 100-150ppm. But then again, ive read its hard to overdose Calcium or Magnesium. Its not easy when you cant judge which information or recommendation has more value than others.
Is there somebody here that can with some authority make a guess if this company knows what its doing? Or am i missing something? It just seems to be different than others.
The bulk of the fertilizer companies use Calcium Nitrate as part of the salts mixed in to create their nutrient line. Calcium Nitrate is 15-0-0 19 percent calcium. The lower level of calcium can also be attributed to using less Calcium Nitrate and adding in some Pure Cal that is lower in nitrogen and higher in Calcium. Calcium is a much overlooked plant requirement and the plant needs more than most realize.thank you. Yes, i cut Bottle A down, now in 6th week flower. using 2ml A and 4ml B. So 16% calcium is nothing unusual? Just for comparison, thats 4 times as high as my calmag, thats only got 4% calcium. guess i dont need that anymore. Now if someone uses the full 5ml A + has a calcium-rich tapwater he will be at 1000ppm calcium or slightly under. Is that not in the overdose range?
I can't say whether they put CaO into these nutrients. If there's an ingredients list, that will tell you. But what this means is it isn't 16% calcium, but about 11.4% calcium. CaO has a molecular weight of 56. 40 units are from Ca, 16 are from O, so CaO is about 71% calcium. 16x0.71=11.4theres CaO printed on the package, im not Dr. Snuggles but that probably means Calcium Oxide. Any trickery in that one? is that recovered by the plant as usual or only in little percentages?
Mannitu68, I would switch to a fertilizer mixed for cannabis. I've used Fox Farm Grow Big on my first two grows. Now on my third grow, two plants at 6.8 pH has "purple" green leaves - indicative of phosphorus overdose lol. Grow Big has 6-4-4. In the old days, the pot growing gurus would recommend a balanced fertilizer, 4-4-4. If you are growing in organic container media, small amounts of N will be fed, so you may need a little less of N in your feed water. Phosphorus is good for vegging plants for up to 2-3 weeks. After this time its good to give feedwater with 3-1-2 ratios. Excess phosphorus will ultimately lower your media pH to too low acidity, less than 6.5. I am currently switching from Fox Farm Grow Big to Botanicare Pure Blend Grow, supposedly formulated especially for marijuana plants. Good Luck to you. To EVERYONE reading this forum, Please invest in a good Practical Botany/Grow Book - preferably one used as a College Text Book. I would recommend The Biology of Horticulture by Preece and Read. DO NOT BUY CURRENT EDITIONS because they are too expensive. Buy the edition not being used anymore because they are cheaper. Another good book, but not a college text although written by PhD in botany, is The Truth about Garden Remedies by Jeff Gillman.thank you.

By the way I would go light with the A bottle because if your using good soil the nutes in there will take care of them for the first four weeksHas anyone ever tried flower fuel it's awesome stuff
dude, the stuff is called "Probud" :)Mannitu68, I would switch to a fertilizer mixed for cannabis
