I also was at the Jack's website checking out their different feed schedules. I have well water. I figured the "city llimit" was for city water with chlorine. I use RO water so I blew right past it.
i tried to call them a few times. no answer. i guess they are shut down for the virus?

but yeah, i'm on well water too. it did say that it's good for water this is higher in pH and alkalinity. i test my well water so i have the actual pH and alkalinity so i was going to ask them.

for flower, it's only the 15-5-20 (3-1-4) and Epsom. i might buy a kilo and see how it works.

any nutes i don't like go to feeding my lawn. lol.

Should be great for veg.

Hmmmm..
I need a little PH up when using RO water with Jacks 5-12-26.

Based on their description, I suspect I might need even more PH up when using a tap formula. I could be totally high. Lol

Very happy with ph stability of jacks. Ph using Megacrop, not as stable....for me.

according to their schedule, they say that "tap" mix is good for most of flower (+epsom)

i use 3-1-2 for veg and it works great. DG foliage pro.

megacrop was the worst nute i've ever used.
i've been trying Ionic Bloom this run and it's pretty stable pH wise.
I got the small bag of megacrop. Gonna use it on my tomatoes and peppers in my garden outside. I have heard some people bragging up mc, and some bashing it, especially in a recirculating system. Not exactly sure why that would matter?

When do I use the 10-30-20 Bloom? What about the Ultraviolet?
When growing Cannabis all stages of growth are important - that's for sure. However if you're getting plants that veg out beautifully but don't bud out, you're grow isn't hitting it's potential.




Our 10-30-20 Boom formula is meant to be incorporated into your grow program to jump-start bud production so you're getting the most flower power possible.
The formula helps send your plants the message that it's time to start delivering on those promises of juicy buds.

We recommend using our 10-30-20 Bloom formula for 1-2 weeks when transitioning from vegetative growth to flower. The formula is designed to shut down vegetative growth and initiative and sustain flower and bud production. It doesn't take long for your plants to make the switch, and after the bud set phase we recommend switching back to your regular program until the "Late Flower" stage.

Be sure to keep an eye on your pH while using 10-30-20 Bloom. Due to the nature of the raw materials that make up the 10-30-20 Bloom, it is potentially acidic, but it really does a great job at letting the plants know it is time to begin producing flowers and providing the necessary nutrients for this transition!

So what about the 5-50-18 Ultraviolet Formula?

That's the beauty of the Jack's Nutrients System. We've designed things to be customizable. While most growers stick to with our 10-30-20 Bloom formula, the Ultraviolet can help provide more phosphorus to your grow during that bud set phase if you really need it. We've seen both formulas turn out top-notch results. Remember they're designed to be used during the same in your grow schedule, but not in conjunction with each other.

No matter which path you choose, we're here to help you every step of the way!

Ok, yes that is their entire line up. It seems to me that Jack's is getting into blending different mixes and labeling them for different purposes. Trying to make a buck I guess? Just like all the others with their "4-20-36" or whatever. They gota snazzy it up for the stoners right? Isn't the point of Jack's 3-2-1 is that you can blend it any way you want? Couldn't you make most of those blends with the 3 base components of the 321 formula and a few other base materials? I am sick of buying 16 different bags of shit to grow the pretty ladies according to some companies feed schedule with 9 different additives.

Thats kind of what I was thinking.. but hey, they are telling you the ratios to use anyway. The other additional products they reccomend now are 1 part though. Your not adding a&b later on, just the 1-3-2 bloom mix. Maybe it has a little bit of calnit mixed in but I thought it was bad to mix them at the same time?

I dunno, the only reason I see to mess with ratios really is to conserve. Otherwise, the way I grow, the plants just kind of take what they want anyway. The same a&b 3/2 mix works fine all the way, even at lower concentrations for me..

I am interested in the 10-30-20 blend, might grab a small bag and test it out. Seems like it would be easier to inject it into a system, no mixing parts.
