Switching to Jacks 3-2-1. What about kelp, silica, and fulvic?

So I have been reading (and reading, and reading) about nutrients and just received my Jacks Hydro, Calcium Nitrate, and Epsom Salt. I'm looking for advice on whether or not I should be using fulvic acid, silica, and/or kelp extract. What brands are you guys using? I want to order asap and want something budget friendly since I am a tight bastard. Also, should it be fulvic or humic acid?
 
For fulvic your better off just buying the Bio-Ag stuff imo. It's really not that expensive for the rate that you use it. For silica agsil16h is about the cheapest you can get. If you're running hydro/coco run it. If you're running soil mix in some diatomaceous earth and if you have time let some rice hulls compost into your soil. Maxicrop has alright kelp, but really if you look around you can find better. I got a 50lb bag of meal for like 100 bucks at a local farm supply place, just Google the brands and do a little reading to make sure you're getting a quality kelp. I think the soluble kelp and liquefied kelp aren't as good as the meal, but you wouldn't be able to use it for hydro really. In that case I believe it works like olive oil and you want the first cold press liquefied seaweed.

Bio-Ag ful-power is what you want.
Fulvic between 2.5ml up to about 10ml increasing up until harvest. My final 2 waterings I use 30ml/gallon to help with a final "flush".

Kelp I'd probably want to give basically whatever the recommendation from the manufacturer is. It's pretty hard to overdo kelp unless you do something drastic. I would definitely use kelp as a foliar spray as well if you don't already. For foliar I use 1tsp/quart but 1/2tsp would probably work just as well.

Agsil16h has a direct calculation to protekt's dilution rate on the buildasoil site I believe. Use it the exact same as you would protekt.
 
On my third run with Jack's, previously I had been using Roots Organics and had surplus Extreme Serene, Trinity and Ancient Amber. I added these to my 321 and my plants always seemed to have issues with deficiencies and looking a bit rough at the end (assume it was PH related and no I do not measure or alter it as I am in soil). This round I decided to do Jack's only with nothing else added and my girls are doing awesome, deep green and the healthiest I have ever run. I have since boxed up all the Roots stuff and put it in the garage. The only thing I have had to alter this run is backing off the strength (while maintaining the same ratio 70% 2.6/1.7/0.8 ) got some slight tip burn on one plant and one was looking a bit too dark. Maybe give it a try without the additions.

Here is my garden from top left clockwise; Desconocida Kush, Purple Afghan Kush, Bubba's Gift and OGK. Two weeks flower.

The jack's hydro is all you need. If you're looking for supplements, look for other mineral salt supplements like mono-potassium phosphate (MKP or KH2PO4).

Sounds like your intention is to grow hydro and mineral salts (particularly nitrate salts) is food for hydro. No need for organics.

Especially considering that you're on a tight budget, avoid gimmicks and tricks like silica tonics. Your plants can't have silicon deficiency.
 
More information on my grow... i am switching from ffhf to coco. The plants are vegging in coco now and doing well, I just want them to grow to their fullest potential. I may go hydro in the future, but I am taking baby steps for now. One day maybe fogponics.

Thanks for any ideas and help, guys.
 
Coco is a good choice. You might want to look into Blumats as well. They will make watering so much simpler. I use a nutrient called Vitagrow which is similar to what you're doing using Jacks and Calcium Nitrate. It's three parts. A = Micronutrients similar to what Jacks Hydro is, Part B = Calcium nitrate, Part C = Monopotassium phosphate. Part a and b for veg and then add part c for flower. The only thing I add is some fulvic acid throughout the grow and Epsom salts a couple weeks into flower. Never have deficiencies or any issues. Sounds like you're on the right path for a simple, high yielding, trouble free grow. Keep it simple. You don't need a dozen bottles of overpriced products to grow good bud. You can buy powdered fulvic and humic acid online for pennies on the dollar compared to those twenty dollar bottles of premixed overpriced wallet grabbers.

Funny you should mention Blumats. I just received my order of 12 blumats, kelp, and fulvic acid. I like the way you think.

Over the years I've tried every method, nutrient line, etc. All I do now is fill a reservoir with with an inexpensive nutrient solution that is all the plants need, set the timer on the light and walk away. I've gone three or four days without even looking at the plants. Just checked the level in the reservoir.
Fabric pots, coco, blumats, and your good. I use three gallon and get great results.
 
My current grow is in 7 gallon fabric pots. They are right at the end of flowering and it seems the pots are wall to wall roots. Mind you, these are in soil, not coco. 3 gallon seems pretty small, but I am new to coco and everyday watering. My veg area is a hodge podge of solo cups, 1 gallon plastic container, and 5 gallon plastic pots. My plan is to grow 4 mainlined plants in a 4'x4' area and 2 scrogged in a 2'x3'.

I personally go with 3.4 - 2.3 - 1.2 and use a mixture of about 60% maxicrop, 20% great white, 15% brown humic, and 5% nano molasses. And GH silicate, it's cheap and 10% silica, so it's fairly strong and 1ml/gallon does just fine veg to flower. And I use coco. Blumats will clog in like two days using kelp, I hand water everything. Sounds like too much work, but I use kelp every watering and it's worth the quality bump for me. And another pro tip, using too much molasses will kill microbial life, go REALLY easy on the molasses in that recipe if you make a batch.

Missing out on organic supplements is missing out indeed! I run dry salts in coco and couldn't imagine living without inoculants of bacillus and myco and a touch of trichoderma. Fertilizers and beneficials work together perfectly well when used properly.

A shot of MKP is good in mid flower but is easily overdone, especially when running with an amendment such as Recharge (which contains all of the above and great value).
 
I run jacks and I foliar once a week with bioag fulvic, nitrozyme(kelp), and I add gro-sil @ under 10ppm, Its like 10 grams per 50 gallons or something small.. The gro-sil doesnt mess with the PH and seems to be a nice pure source of silica. This is in flood and drain.


Budget friendly option is kelp4less foliar pack. They have a nice blend of fulvic, humic, and soluble kelp. I'm gonna switch to their blend when my bottles go empty
