Homebrewer, at the EC that you are running, why do you have leaf tip burn?
Dyna-Gro vs Advanced Nutrients Connoisseur (AK47 Grow)

Homebrewer, you use a 600W light right? In the picture it looks so far from the plants, do you just move it for the picture or do they look that awesome with the light at that distance? How long do you veg for? Right now I'm at (5L Water in the res/Plant) what do you use? I do a res change every 2 weeks and have steady ppm but since still trying to use up the Dutch Master Gold have to adjust the pH daily.

With the 1-1-2 NPK ratio, the tip burn could be from too much nitrogen at the later stages of flowering. At this ratio, more of my total ppm is made up of N than I've ever run before this late in flower. Even with the GH 3 part, I would cut back the micro (5-0-1) because the plants simply don't need all that nitrogen. The plants aren't producing leaves or stems like they are in the first 3-4 weeks but Connoisseur's formula continues to hammer home poor ratios.
The 600watt light stays roughly that distance from start to finish, it's never been moved for a picture.
I veg until the plants are a certain height, I like about 15 inches.
My res in veg is 12 gallons and about 15-18 in flower. I change both once per week. pH is something I almost never even look at anymore. If I go half a week then decide to check it, I usually shake my head and say to myself 'friggen DynaGro man' just as an expression of how my pH is ALWYAS stable with this stuff. It never ceases to amaze me. Connoisseurs' stability isn't bad but it does need adjusted a few times per week.

HB- it's interesting to watch you navigate through your own self created dilemma. You set a good example of how to read your plants and attempt trouble shooting them. If anyone has a good shot at a final outcome with those conoisseur plants- it's you. Fingers are crossed for ya...

Thanks! I used to participate more around the forum but arguing with kids with seemingly no experience, journals or pics of their plants got old real quick.

And there's always Ocalli...
HB- I will be using dynagrow in the new HPA system I'm building right now. It will deliver sub second 50 micron blasts every few mintues or so at 100 psi. I know it's kinda overkill, but the reason I got back into this was so I could play around with new technologies. The outline of the system is in my sig line (I undertand if it's not your interest). But I'll let you know if Dynagrow also proves to work in the HPA arena as good as it does here... -I don't see why not...Also, wanted to post this about ammoniacal nitrogen, plant stretch and phosphorous because I've been told Dynagrow is mainly for soil due to the nitrogen it uses- but this paper seems to explain it is misinformation:

Anyway- the proof is in the pudding...

Came across this nute comparison thread which includes DynaGro.

I guess we'll take him at his word since he 'tested' eight different nutrient brands yet failed to post even one picture??? I'm also wondering why his gpw measurements are so low, new grower maybe?
EDIT: One thing I also noticed is that he was running 12 plants per 1000 watt light, 8 lights so I'm assuming a different nute line under each light. His DynaGro average is under 2 ounces per plant and I easily exceed that with 9 plants under 600 watters. So again, newer grower?

Yes, there is no proof that his conditions were scientific at all. I would just write off the author's opinion compared to yours. We know more about your growing conditions, and specific "control" measures. We have pics and writeups on your final result. There is so much to methodical scientific testing, and I'd tend to think most people writing about nute growing comparisons are not even close to properly equipped to have the controlled environment with absolutely no other variables involved. And without that- their tests are basically worthless... All that matters is that you are happy with your results, and I'd think you are... All that said, it is possible to become emotionally involved and only see the results you want to- but in this case- we must all be duped?

New to the forum and very glad I came upon the posts by Homebrewer. A little off topic but could anyone recommend a feeding schedule with Dyna-Grow? I use pro-mix and rain water. Need to know how much to feed and how often to feed it. I tried the 1/4 to 1/2 tsp/gallon with every watering and it seems a bit too much. I also use pro-tekt at 1/2 tsp per gallon.

It's here, (multiple times I think). Look back a few pages, and enjoy the thread- it's a good read and you'll learn alot...

My goal in this test or any that I run is to be honest with myself and to just post the facts as I encounter them. I was a GH 3-part fanboy, tested DG against it 10 months ago and now I exclusively use DynaGro. So I'd like to think that I'm pretty open to results whether they're positive or negative.
On a whole though, I'm always skeptical of posters who make claims and don't post pictures. Maybe a grower swears by molasses or whatever, ok, post some pics, lets see what you think it does. When they do post pics, you gotta ask yourself, are those plants extraordinary? Have I achieved the same 'results' with appropriate feeding levels and a healthy environment? Those two things go a lot further than 90% of the growers out there realize.
Feed, feed, water OR feed, water, feed, water. I like about 3mls of base nutes per gallon. Maybe 1ml of grow and 2 of bloom. Protekt is a nice additive if you're using rain or RO as it will not only balance the pH but it will benefit your plants.

I played with the cannastats nute calculator http://www.angelfire.com/cantina/fourtwenty/articles/download.htm (it's pretty nice- especially for mixing different bottles and getting the final results). Punched in your bloom formula Homebrewer:
(ml/gal)
Grow 2.5
Bloom 7.5
ProTekt 5
MagPro 1.5
Got a theoretical ppm of 1213 on the .7 scale and here was the breakdown individualized element tds:
NO3: 78, NH4: 37, P: 156, K:180, Mg: 21, S: 8, Ca: 53, Fe: 2.64, B: .528, Mn: 1.32, Zn: 1.32, Mo:.024, Na: 2.64, Cu: 1.32, Cl: 2.64, Co: .04, Si: 103, (Calc doesnt have a spot for nickel).
Dynagrow is definitely different as compared to GH (which has lot less P, and less micros). I read here that P is likely the main nutrient contributor to plant stretch: http://www.onhort.com/What-Really-Causes-Stretch-article2891
So I wonder if Dynagrow gets the plants to grow fast, then buds fill in good during the flowering stages with their mix of micros... Just a thought as to what their strategy is and why it works...

Your plants aren't taking in everything you feed them as there is always ppm left in the res at res change time. But I think as long as you feed modestly and have an idea of what the plants need at the different stages of flowering, your plants will pick and choose what they consume and do so when they need to. Connoisseur doesn't allow any 'tweaking' of the part A and B as they both contain minerals plants need and are 'designed' to be used in equal parts. At this stage, I wish I could supply less nitrogen while keeping the secondary macro and micro nutes stable, which is exactly what I'm able to do with DynaGro. I believe the mineral makeup of my res is more desirable when I'm using DG and the plants respond with bigger yields and better overall health.
Chronic update from seed in the dirt, day 43 I think, DynaGro base nutes only....
