dang its that blue dye again in the finish. my worst enemy.
what are those little balls.... i always thought theyre calcium nitrate

The balls are the calnit. That is what the bag of calnit looks likedang its that blue dye again in the finish. my worst enemy.

That I'm not sure of. I'll have to ask Peters about that. You're right though. They look just like calcium nitrate granules. First thing I thought when I saw themdang its that blue dye again in the finish. my worst enemy.

Negative. Jack's 7-15-30 contains 0% calcium nitrate.The balls are the calnit. That is what the bag of calnit looks like
Well then. They sure look like it.Negative. Jack's 7-15-30 contains 0% calcium nitrate.
You're right. They look exactly the same. The blue dye is going to take some getting used to. It is very blue like toilet water biscuit blue. I have the urge to take a piss every time I see the reservoirWell then. They sure look like it.
Not a huge difference. Note, Jacks is virtually all Nitrate, the "finish" N is split between Nitrate and Ammonical. Not sure what the Ammonical does.well thats good to know that you can pretty much mimic the 7-15-30 formula. cuts out an extra bag and saves some money in the process.
5g of Jacks + 1.1g of Epsom roughly = 7-15-30?
@TintEastwood can you doublecheck the maths on it?
i think thats what ill do then if i like what i see from the Finish formula when it comes in a week or two.
One big thing I noticed is the increased amount of PH up I have to add with the 7-15-30 versus the 5-12-26. I normally add 2ML of highly concentrated PH UP to a 32 gallon reservoir to bring the PH to 5.8. It took 6ML with 7-15-30. I was kinda blown away. Very acidic stuff. Hopefully all that sulfur amounts to lots of stank and frostMy guess is they used ammonium sulphate to increase S, the NH4 was more a consequence of the choice of chemical than an elemental target.
Thanks man. It's a lot of work but I really enjoy gardening and sharing tips with other growers. It would be a good idea to mix your jack's, epsom, and calcium nitrate in a holding reservoir to ensure everything is mixed properly. You can also verify PPM is in your desired range and PH is properly adjusted to your liking and then safely transfer it into your system once all your parameters are optimal.Wow looks delicious. Thanks for sharing all your info. I'm just making a RDWC setup myself right now. I have been reading up on Jacks today. I want to jack it also I think. I have no hydro experience. First question. I have 100g setup in the mix. 4 x20g Tote + Res. So if I weigh out the vege solution to the 100g to (X) gram ratio they have on the feeding schedule, can I add that whole weight to my res with RO water in the system already? Or should I get 100G holding tank to mix everything then transfer all of the water to my res? Also after I drain the system how long before I have to have water running in it again for the roots?
My 7-15-30 has blue dye. I received my bag about 2 weeks ago from jacksnutrients.com. The 5-12-26 is a light brown shade when mixed with water.hey jonny when you mix the 7-15-30 is it blue dye in the rez because i msgd jacks nutrients via email and they said the 10-30-20 is blue dye but the 7-15-30 isnt blue dye.
i finished up my RO formula and bought the 321 cause its going to be clear water so i dont want to have all my filters and fans getting blue again if i use 7-15-30. its just too damn messy.
I keep Southern Ag's biological friendly fungicide on hand as well as 34% h202, but I presently do not add either to my reservoir. BFF can be applied at 1ML/10 gallons. It's the same ingredient as hydrogaurd, but more concentrated. 34% h202 can be applied at 5ML/gallon if there is a root rot issue to resolve. h202 is the heavy artillery. Kinda pricey to add to the res on the regular, but it can be done. BFF is very cost effective to add every res fill. Also, many people use pool shock (aka calcium hypochlorite) for sterility. 24g/to 1 gallon RO water. Then add 1ML/gallon of shock solution to your res. Cheap and effective.Much love, may I ask. What are you using for root rot prevention ? I have read hydro guard? And what using to sanitize hydrogen peroxide? I have read to leave the nutes in the res for 2 weeks and then replace. What is your recommendation?
