After reading thru the thread again, I may try modifying my mix. I have been mixing 1:1 Jacks/Calnit and feeding at 1500 ppm. Will try 1/.66 5/12/26-CaN ratio, did notice some off coloring on some leaves I was thinking was MG def.

I feel the 1/1 ratio has too much N. Your plants will get greener but they will not be as healthy. What happens is that too much NO3 leads to the plant forming free amino acids instead of complete proteins. In fact, I feel, it is better to be slightly low on N as that insures complete proteins provided you are not shorting the plant on other elements. Nitrate sap testers will let you know.
Go to the 1/.66 ratio and see if your plants growth rate doesn't improve. |

Yo Sam, nice to see ya over here. I have been following this info from GC, mainly CropReport, Delta, and Healer's threads. Good to see this info over here!

@ *mistress* (or others)
How important is feeding the cal-nit separate from the 5-11-26? If i need x amount of water per feeding, do i feed .5x of the 5-11-26, then .5x of the cal-nit (with the proper amount of each of course)? |

space case...i have a journal over there, yo's 15 kw medical grow
basement...you can combine them in the same res and feed them together. They come separately because they do not work well in concentrated solns, precipitation will occur...but not at the concentrations we use. what you do is add your water, then add your 5-11-26 and mix it completely in and finally, add your CaNO3. Then check your pH and adjust...but, next time if you have to use pH down add it to the water before you add the hydro special...if you have to use pH up add it last. |

YosemiteSam - If you don't mind.... What medium are your girls in? When not playing with organics, I like straight coco run DTW. It seems this mix would be just fine for coco, but I thought I'd ask your thoughts on that.
Thanks! |

I use 5-11-27 with calcium nitrate, epsom salt and potassium phosphate for years. Did side by side with pureblends line, AN, Canna, and FloraNova with all there bells and whistles over the years none were any better. I just ran it at 800ppm. I did the calculations once it cost me like 0.06 cents I think per 10L where as FloraNova was the second cheapest at like .60 cents. Even for a small grow that adds up. It also allows a lot of control. The N to K ratio really is good at controlling hight. Want shorter plant add more K or less N. I have read a lot of studies that show high N is a big factor in pest control. High N plants are more attractive to bugs. I think you can tell that by just looking at them all that very weak fast grow just makes for weak soft plants.
I have run this in peat, coco, hydroton and straight water culture, always works great. I am really suprised that more people don't use it. I have tried to get other people to use it but no one does unless I mix a stock solution for them, then they love it. I can see why a lot of people have got into the nutrient business from this experience. Just go by something at 1 dollar through it in water and sell it for 10. |

straight coco dtw...sunshine just coir, no treatment necessary other than taking a sample of each bag and checking for excess Na before using. i am in 20 gal smart pots...i believe they will support 3 pound plants given enough light.

Brilliant! Thanks for all of the great info in this and many other threads on IC.
I have had some rediculas results on coco - dtw in the past. Think I'll be going back. While I like the whole organic experience/process overall, I had been avoiding the straight coco largely due to a lack of supplies in my current area of residence. I have sourced good cheap coco and your guidance with the Jack's has provided that last piece of the puzzle. I did not wish to order on-line for bottled nutes. The Jack's is too easy and cheap to pass up. Thanks again and many regards. |
