3 days on jack's 5-12-26 and the plants are loving it! Bye bye General Hydroponics forever

Calcium nitrate as the nitrogen source eliminates the need for calmag.



Interesting. I've grown the Nirvana Maui Waui. I don't know how authentic it is but it's some decent weed.

I'm too simple minded to know the difference between "authentic" and "not authentic." If I buy seeds and they say maui waui I had better taste some got-dam fruit of some kind when I smoke a bowl. That's as complicated as satisfaction is for me. I really think people get into the weeds on "authentic" designations. Some of the best dope I ever grew was from random bag seed that hermied. How's that for authentic? :)

Seriously though someone asked me what strains I had and I mentioned maui waui. The first response I got was, "is it real maui?" I just shake my head. Dude stick your nose in the bag? Now smoke a fucking bowl. Authentic enough for you? :) It truly does look, smell, and taste like maui waui. If it's a con-artist-maui-waui-look-alike I'm more than satisfied with the knock-off ;)

12oz Kit Jacks 321 Hydroponic Fertilizer Nutrient Plant Food Grow Bloom General | eBay

Versatile can also be used as a "normal" fertilizer for plants growing in soil. One of the "guru" pioneers of COB (chip on board) LED lighting applied to indoor growing kindly authored a comprehensive technical appraisal video of Jacks 321, what it is, how it works, why it works so well etc.

I just picked up the same "kit". I keep reading about how happy everyone is with Jack's, so I wanted to get in on the fun :bigjoint:

Jack's could have more calcium in my opinion. Maybe flowering cal-mag (no N) would be good to use during flip and stretch. I also think a PK boost after the 4th week is beneficial. If you have extra maxi powders, you can combine them and add a small amount of cal/nit to form a nice nutrient profile of around 145 65 184 145 60. Slightly superior numbers than Jack's I think. However, you can also manipulate Jack's with flowering cal-mag + mkp so "who cares". Nice flowers.

Jack's 5-12-26 has no calcium. It's provided by calcium nitrate as part of the 3-2-1- system. If you need more calcium you add more calcium nitrate. That's what makes the 3-2-1 system so great. It's flexible. Need more magnesium sulfate? Add more epsom. Less? Decrease. Again, this flexibility is what makes jack's 5-12-26 and the 3-2-1 system such a powerhouse performer for hydroponic gardening.

I disagree. That's why almost all dispensary pot tastes like crap. Flowers loaded with potassium and phosphorous burn and taste like shit. The best burn qualities, flavor, and yield will be obtained by providing a balanced fertilizer start to finish. I recommend you attempt this once before over complicating things. You'll be pleasantly surprised by your results. PK boosters have always been unnecessary, but the fertilizer companies continue to perpetuate the lie so they get to sell you another product that vastly increases their profits. As the saying goes, "It's all about the benjamen's." They'll keep the lie going as long as the uninformed continue buying their products. It's a vicsous circle that never ends, because people refuse to wise up. I fell victim to the same con. It took me 2 years to realize I was only fucking myself and over complicating my garden maintenance and life in general. Jack's produced the most flavorful pot I have ever grown in a hydroponic medium with the most desirable burn qualities. Nobody could tell whether it was soil grown or hydro, because it tasted that fantastic. You'd be shocked just how tasty good hydro can be when you aren't loading the plant up with unnecessary amounts of P & K. Word to your mother :)

Holy Christ just reading that paragraph gave me a headache and left me in a state of confusion. My friend you really need to simplify your life. I recommend you start Jack'n it every day 3-2-1 style and for the love of god don't fucking over complicate it ;)

I am aware of how to alter salt inputs. I've used jacks and grown great cannabis, but have also used GH powders + liquids (lucas formula) and achieved similar results and a great burn/flavor profile. Jacks 3-2 doesn't have an ideal amount of calcium without oversupplying nitrogen for some strains during stretch in my opinion. Tissue samples from cannabis confirm there is a spike in the requirement for P and K after week three. Ideally, you stop this by week 6 depending on finish time. You could also lower cal/nit during this period. I am unsure why the last paragraph left you in a state of confusion - a good target for cannabis crop N-P-K-Ca-Mg is 150-50-200-150-60. I am glad it has worked out for you but there are science-based approaches to push results further. I think adopting a Cal-mag supplement that doesn't have nitrogen is a good, simple way to take jack's to another level when the plant is yearning for calcium at the start of flower. Particularly, if you're growing a type that doesn't enjoy excess nitrogen in cal/nit. These small inputs are nice to have in the toolbox when used appropriately. Other than that, jacks is a solid base nute.

I'm a very simple minded individual and I mean this with all sincerity. I don't desire to push the limits. I just want simplicity because that's what works best for me. I can see you're one of those folks that really likes to break it down to the nuts and bolts and I can dig that. It's just too complicated for me and I would only wind up fucking things up. For a bone head like me I truly need something simple, and that's what the 3-2-1 system provides. And it's cost effective to boot. The nitrogen content of calcium nitrate has been a valid concern among jack's growers since it's introduction, and there are some people that use a variety of other calcium sources to omit the nitrogen. I achieved somewhere around a .75 GPW off of a single 600w lamp with jack's 3-2-1 system without altering the recipe. I did a 3 day flush at the end and that was all. I am more than satisfied with the results in flavor, yield, and burn qualities and I want for nothing more. Again, I am just a simple minded bone head. I need simple because if it were anything but I would fucker it all up :)

you're assuming 321 doesn't have enough P and K. so your premise is false.

Your plants will benefit during week 4-6 with the addition of MKP. Will they work without it? Sure - but you'll have a bigger yield adding monopotassium phosphate on top of your base nutrient when demand spikes. You can do other things to increase yield i.e. raising RH into the 70s, leaf temp to 80, slightly higher if running LEDs, Co2, and so on but MKP in addition to your base nute timed right is invaluable in my experience. Cheap and effective.

Fair enough - it's something to maybe explore once you're dialed in and looking to experiment.. or not. Still simple salts but cool to see simple things benefit yields.

Wouldn't lead temp in the 80's reduce terpene levels?
