My experience with Jacks:
Id keep the formula the same except 1.8 grams on the cal nit. As long as the salts dont get wet they will last for years in the home depot 5 buckets with spin tight lids. I went with all food grade salts they are one step better quality above greenhouse grade. This formula will work all the way through from veg through flower. I mixed in 40 gallons worth of nutes in 55 gallons of water to dilute the solution slightly. Your plants will tell you what they need if you know how to read them. Dissolve Jacks then epsom and then booster and lastly the cal/nit. I would use seagreen every thursday and ogbiowar tea every monday. Foliar your veggies with these as well. The bloom booster should be uses at half strength during week 4 and again at 3/4-full strength during weeks 6-8. Water till it flows out of the bottom of the container. Coco holds on to Jacks like you wouldnt believe. Honestly though if your nutrient bill is that low for a year I wouldnt worry about your cost as much as I would worry about its quality and what it does for your bud. Maybe Canna or H & G would cost you more but you will probably get better results. If you want quality you only need to run an A, B and cal/mag and your plants will do great.
I'm thinking about making the switch to Jacks pro, the formulas I've read have varied quite a bit, but I was going to go with the basics per gallon:
3 grams Jacks hyrdo
2 grams Jacks calcium nitrate
1 gram Epsom salt
.5 gram of Jacks blossom booster (starting at three weeks flower)
Yes and no. I've been using walgreens brand epsoms because its on my way to work and its cheap. What I prefer is a brand that dissolves quickly because at the moment its the only salt compound that I don't make stock solutions with and I dissolve it everytime I mix a rez.Does it matter which brand of Epsom salt I purchase?
Due to Coco's ability to hold on to salts and the build up properties of Jack's, what EC would you recommend in a flood and drain situation. I was running about a 1.4EC, everything looks great, although I am not seeing the weight pack on like I did in a top feed.
cool, thanks for being a dick cap. Ive got 2 runs through and all though thats not a lot it was enough to do some experimenting. I ran my tests and kept notes on the results from 9 different strains. I dont claim to be an expert you can take my info for what it is but if you dont agree at least say why? By the way my local hydro shop just started brewing their own teas and they are better and cost less then ogbiowar I guess that little comment was the push I needed to make the switch.
Thanks bro,@GR33NL3AF Nice mother shot. You're associated with MonsterGardens, right? I've gotten some great info from your videos, thanks man. How do you feel about Nectar of the Gods? The video was very informative, albeit over my head somewhat.
If you go back in this super long thread to the beginning it will take a turn towards that. Once you can work a nute calculator, you will quickly figure out that jacks does not quite have the flexibility you need to dial shit in. You need a few more salts.
I'm guessing the undercurrent system is true hydroponics- like Nutrient Film Technique? If thats the case then I would use less magnesium. You can probably drop the epsom salts down to .5 a gallon.So I've been using the 3/1.8/1 ratio and its working well for me. I notice alot of you guys are doing coco, and I'm in undercurrrents. Is there any advice anybody wants to recommend for undercurrent? Anyone with experience running undercurrents and jacks?
As I understand it Magnesium is a Potassium protagonist- it helps the uptake of Potassium.
Here is mulders chart. Fat arrows show stimulation, and skinny ones are antagonism.
Basically, all of the nutes play off of eachother. If you have too much of one it leads to unavailability of another, or if you have some of one, it can lead to even more uptake of another. Thats why RATIOS are so important.
Are all plants similar? sure... but surely they do not all require the same needs. I have worked aroudn plants in the nursery industry for 10+ years. Azaleas have a different diet than say... palm trees.
I thought I would post it here for everyone.
I realize that you have to hit the tip of the iceberg first. This is just a start for me.
