Hey guys Im growing in coco and looking for a Jacks, CaNO3, MgSO4 and MOST formula to start my new cycle. I have been using Flora Micro, Flora Bloom, Calmag, big bud, bud candy and overdrive. And the occasional superthive. Im hoping the Jacks will do just as well. This will be the first time Ive switched my nutes in 5 years. Im a little nervouse I must admit but at $200 for a full grow compared to $1600 Im willing to give it a try. Im looking for suggestions on where to start and how Jacks does with coco. I will be mixing the jacks into 5 gallon buckets and then mixing it into a 55 gallon reservoir. Do I mix the Jacks etc.. into the 5 gallon bucket at the 55g strength and take my ec reading from that or do I add Jacks to the rez and keep adding until my ec reaches the desired level? Any info would be helpfull. I have been reading a lot of Jacks threads and while there is a lot of formulas for DWC there is not much info on COCO formulas. Thanks Everyone!

@thewhitelotus you can get CaNO3 at MBFERTS.com for $23 free shipping for a 25 lb bag. I just mixed up a 5 gallon practice solution to run on one of my flowers just starting week 4. I used 2.5 grams Jacks, 1.67 grams Cal/nit, .5g epsom and .5 grams of MOST. My PH in RO came out to 4.9 and 740 ppm with an EC of 1.5. Any ideas? Why is my PH so low?

Surf,

I ended up getting the CalNit from JR Peters as well as the Jacks. I made stock solutions of each and now just use about 9ml/gal of each and that puts me right around 1.0 EC and i add a little PH down to get it at 5.8.

I took the advice from IC "So 145 grams of calcium nitrate in a jug topped off to a quart with RO water. And 220 grams of Jack's 5-12-26 in a jug topped off to a quart with RO water. Then use 10 ml of each per gallon of you nute solution. "

Are you using tap water or RO?

Im using RO. I might try to mix a stock solution as well, should I still weigh out my epsom and MOST and mix in per gallon?

[thewhitelotus]

It might be the RO.....i use my tap, which is pretty high PH (around 8.0)but very clean water. I use ph down still after adding everything because of how high my tap ph is..
