Yes Jacks 321 is the only thing I use. I used to add various 'enhancers' to it but when I came clean, things just went right. I also really recommend the HLG QBs for lights; they have some with added red now. I run them very soft, each bar has 3x V2 288s and I turn them down so it only pulls 200W total at the outlet.

Yup.. i use QB's.. just not HLG.. same product can be bought a lot cheaper :) I just didn't get as many as you did. Well.. i was wondering why my yield isn't awesome and since we use the same nutes in the same way.. i need more light.. one day...

P.S. 3500k?

I do not worry about some slight claw and very minor tip burn, they usually grow out of it. If anything on this last grow from earlier in the year I should have kicked up the strength. They really faded at the end, however maybe that was perfect as all of them in that batch were my best. Everyone in my circles said they were topshelf and matched anything at the dispensaries (which around here are everywhere). Here are some of my final pictures before chop.

Cool. I just had to ask about the minor "hooking" because they look 'perfect' and healthy and I was curious about your experience and thoughts. Those plants look fantastic, especially that first pic.
Thanks dude.

What driver are you using (per three 288s)? And do you know roughly what ppfd you're around - I'm curious for veg actually. Saw some weirdness under 288s that I'm wondering now if it might be *too much* light.

Thanks again.

It's not the same product, to be fair, though. It's a clone/copy at best. Not shitting on whatever you've got, just saying.

How is it a copy at best when it uses the same exact parts? I am not arguing, am just curious...
 
Honestly, I don't wanna argue either. I think it's pretty straight forward. :)
I shouldn't have said anything, haha.

Meanwell HLG-320H-C1750B

FYI I bought these lights from Timber Lights, 3SMAL as it were. I kept looking at all the features I wanted and just decided to go Lexus. Highly recommend them.

And fuck it here is my current grow, one week into flower.

Cool, thanks.
 
Hey guys, I have been checking out some of your results with jacks. Looking really nice. So I was checking out feeding schedules and nutes. They listed "sierra natural science" (sns 209) listed as a pest deterrent? Do you have any experience with this magic deterrent, or just more crap?

Hand watered? Coco?

Sorry I missed this. Yes I hand water and use Roots Organic Green Lite soil which is coco based. I amend it with some stuff leftover from my organic days: Crab Meal, Kelp Meal, Insect Frass, Earth Worm Casings, and Azomite Powder.

Why is there a JR Peters Jack & a different Jacks now? I bought the newer one yesterday. Says Boost on the side of all 3 bags I bought. Got the clone starter mix, the Part A (123 base?) & the Cal-Nit. Epsom is on order. Got the big 5 pnd bag of PowerGrow Epsom that GG linked.
This is still JRPeters, just slightly altered correct?
20191202_132850.jpg20191202_132911.jpgAs many may know, i battle LedDefficiency using TechNaFlora & Epsom, 50% of the time.
Remembering SixStrings introducing this product (first i heard anyways) when he made himself know with his steller Cob grows after making the switch.
He used 123 & Ionic here n there. Nothing ever mentioned about micros or fulvic but i do appreciate the breakdown GG does on it all. Makes sense.
 
I use the two on the right + epsom for my coco/cmh grow. The part-b is cal-nit, like epsom, not proprietary.

As needed to bump up ca/mg, I use Calimagic.

Yes, it's Jack's new packaging as far as I know. Part A is "Jacks Hydroponic 5-12-26", and Part B is "Calcium Nitrate".
I remember thinking I'd heard something about the "new packaging' that made me search for it specifically (slight alteration of formula or something like that - I hope someone who knows will chime in), but I couldn't find it.

Like Tint said, the only thing Jack's brand that you need for "Jack's 3-2-1" is the "Jack's hydroponic 5-12-26"/"Part A". Then you can just use any Calcium nitrate, and epsom salt (magnesium sulphate) brand you want.
 
without any additives I am getting some nitrogen toxicity on one of my girls using Jacks. I dropped the calnit by hald and it looked good in the morning but come afternoon im getting the dark tips on even the new growth... any suggestions? I am considering dropping "part b" and using a calmag with lower N. Can I do that? Any inputs? Cant say I am sorry for unearthing this somewhat dead post but I need answers. Thanks all

Reduce the cal-nit a little. I had to make a few small changes to get the average to work on my multi-strain garden.
