General Hydroponics

I just bought the 3 part nutrient line from General Hydroponics (bloom, grow, micro) to try it out side by side with my current nutes to see which I like better. I am running it in RDWC. I have been tipped off that the Lucas formula is a good way to mix the nutes, but as it uses only 2 and I have already bought three I am looking for a few different options. Here are my questions.

1. Can you recommend a chart or sight that has a mixing guide laid out that differentiates between Vegetative and Flowering stages, that uses all three, and that you personalty have used and know to work well?

2. Should I just mix to the specifics that GH give me and not go for a "home made" mix?

3. Is it cool to switch to these nutes mid flower cycle during a regular nutrient change or should I hold off and start a clone fresh with only these nutes?

Thanks!

if you want to be more scientific about it get two plants and (if you still have the old nutes) feed one w/ the GH and the other w/ your old stuff, and feed them the same ammounts. as far a Q2 i would use a home mix, or just the lucas formula. ( i understand that you want to use all three) Hope this provides some insight ;)

I use a modified version of the Useless Formula. The nice thing about GH 3 part is that it is highly customizable and adjustable. I started with his basic recipe and tweaked it depending on what the plants wanted and how long they go. I don't uses H2O2 and use Kool Bloom powder for the booster week. I also use Koolbloom, floranectar, cal mag, and flora blend in varying amounts at various times. Hope it helps!

Bloom
week 1 6-6-10- 800/1200
week 2 3-7-12 - 1000/1400
week 3 3-8-14 - 1000/1400
week 4 3-8-16 - 1000/1400
week 5 (discussed in detail below*)
week 6 0-7-20 - 1000/1400
week 7 0-6-20 (see bleow**)
* During week 5 if not using a booster like Superbud, Bushmaster Kabloom etc. run 2.5-7-18. I use MOAB (Mother of All Blooms) or BushMaster at 50% of recommended strength, and use 1.25-3.5-9 for the fert base.

At every ressy change out I add in 5 drops per gallon of 35% food grade H2O2. During flush use ph adjusted water at 5.5-6.0
I will add epsom salt at week 1 of bloom if the plants are heavy feeders AND I see signs of an Mg def. Otherwise I won't use it. The only time I have ever had Mg def is during transition. The GH 3 part is a little low on Mg, but the PBP and Canna nutes are way lower.

Here's a 10 weeker I found on another forum that is also a decent base. A bit on the hot side, but great for heavy feeders.

Bloom -
week 1 6-6-10- 800/1200
week 2 3-7-12 - 1000/1400
week 3 3-8-14 - 1000/1400
week 4 3-8-16 - 1000/1400
week 5 3-8-16 - 1000/1400
week 6 3-8-16 - 1000/1400
week 7 (discussed in detail below*)
week 8 0-7-20 - 1000/1400 Only Floralicious Bloom & Liguid KoolBloom

week 9 and 10 - plain ph'd water

* During week 7 if not using a booster like Superbud, Bushmaster Kabloom etc. run 2.5-7-18. I use MOAB (Mother of All Blooms) or BushMaster at 50% of recommended strength, and use 1.25-3.5-9 for the fert base.

All of these but the (powder kool bloom or MOAB) listed below are to be in conjunction with the GH3part up untill week 7 in bloom.

200ml of each for 40gallon reservoir

CalMag 5ml per gallon
Liquid Kool Bloom 5ml per gallon
Floralicious Bloom 5ml per gallon
Flora Blend 5 ml per gallon

*Dry KoolBloom 2 1/2 Tablespoons per 40 gal rez

PH 5.5-6.0
nutrient temp solution 68-72 deg

I use RO water so Cal Mag is a must

Good to know, I have about 3 weeks before I can get two plants going into flower the same day, and once I do I will be using one with the tried and true Technaflora formula, and the other will be the GH. This way I can have a good side by side and see which one seems to be the best. I only have 1 6 bucket UC system built as of now so the two test subjects will be in individual DWC buckets, just the air stone.

Also, this is my new room, just finished it up today, I will have a new video up tomorrow with all my girls. well I was cruising youtube before and copyed the wrong link, here is the one of my set up sorry http://www.youtube.com/watch?v=w4DXt020pL4 if you like it feel free to like or comment.

No way dude, if you do that, you'll have an insanely high PPM. you better start low with that stuff. I run the 3 part series as well and the calimagic.

Yep, you can switch it up. I suggest going with the 3 part series.

Your veg and flower ratios will be strain dependent. An example of mine though run on an AK-47 strain, which are really sensitive to nutes:

4/2/2/2 veg

2/3/4/2 flower

grow, micro, bloom, calimagic.

veg weeks 1-2: 150-200ppm
veg weeks 2-4: 200-400ppm
veg week 5: 400-800ppm

bloom week 1-2: 400-800ppm
bloom week 3-4: 600-1000ppm
bloom week 5-6: 800-1200ppm
bloom week 7-8: 1000-1400ppm
bloom week 9 (if applicable): 1000-1400ppm

Also, I don't change out my res completely. I transition the ratios as the plants transition. Basically a mix transition as well.

I've been doing some research in the Lucas formula. Several sources say to use 5-10 for veg and 10 -16 flower but on the lucas site itself it says to use 5-10 in both cycles? What do you use? And considering how cheap this formula is to run compared to any other worthy competition, can you recommend a good additive or two, preferably something that I used in only veg or only flower? http://www.youtube.com/watch?v=w4DXt020pL4

Just remember, these figures are strain dependent. My AK-47's cannot run anywhere close to that high of PPM. The Rick James though, absolutely will. So, careful, less is more. Nute burn is a rough thing.

I am not looking for something as complicated as that. This will be the first time I am not using a manufacturer recommended formula. I will be using the will be using the Lucas formula, most likely 5-10 mlpg for flower and veg and I will try and add 2 additives to it for veg, and a separate 2 for flower, any suggestions there? I understand that a formula as the one stated before can be much better, but it is also complicated, I am trying to grasp and use a home made formula from the ground up, I don't feel to confident jumping into an advanced mix that is week dependent .

It's not "week dependant". It simply allows you to fine tune your feeding.

Hey guys,
i m just start a new grow using a modified lucas formula with ro water.

I m using during grow 4 part of micro and 3 part of bloom (dont use grow because micro have enought nitrogen) and during flowering i will switch to 4 part of bloom and 3 of micro.

Then i watch ec for now how much nutrient i need to put.

For first 3 days 300-400 ec then increase to 1000-1200 in the next 2 week.
For flowering i menage to start at 1000-1200 then arrive to 1600-1700.
If u want u can lower ec in the last 2 week for flush.

If u want u can follow my grow log and see what happen using this formula: https://www.rollitup.org/grow-journals/607823-nl-5-x-haze-atami.html

Enjoy

I am glad you said that. Diving right in can be a bad idea!!! If you have questions, don't hesitate to ask. I run the GH line because it is tried and true. Love the stuff.
Well I have been using Technaflora "recipe for success" with the addition of only Rock Resonator in bloom. I am a big fan of the addition and I will most likely use during flower with the GH. Right now what I am looking at is 8-10 mlpg for flower and veg, with the addition of the RR. I would prefer one more additive for veg, if for nothing else than to keep my "veg should be different" feeling sated. Any ideas on one or two good things to add to this mix?

I know. That's why I said this, "The nice thing about GH 3 part is that it is highly customizable and adjustable. I started with his basic recipe and tweaked it depending on what the plants wanted and how long they go. " I have probably a half dozen different plant specific nutrient profiles that I based off of Useless. Some ended up close to the original formula, some ended up quite different.

Exactly. In fact if you look at the weeks closely you can see that many are the same or very nearly the same. It allows you to fine tune the nutrient levels and ratios for any given plant variety. It's much more adjustable than Lucas, and the additives are not necessary with the possible exception of the calmag. But even that depends on your plants and water supply.

My Blue Dream and Girl Scout Cookies don't need anywhere near the amounts my OG's need.

Sounds like we agree. :D
 
This is a great post. I am struggling with the GH line. I'd like to ask some pros if I should use Cal Mag through the whole grow? I especially am confused on nutrients during the first two weeks of veg, what ppms I should shoot for, how much Cal Mag?

My understaning of the Lucus formula is its a money saver that CAN be as good as the 3 part. But its flawed. The idea that you dont use Flora Grow so you save money, But only Grow and Mico have N, so you dont use Grow then you Double your Mico to get the N you would of had with Grow. The probelms is you use 2x the amount of Micro, so you are not saving anything. If your not saving money I cant see how dropping Grow will make your Grow better. GH Flora serises is made to work togthers, you need all 3 parts, When you Cut Grow not only do you cut N you also cut out the Mag thats in the Grow part.

Like others have said you can really customise your grow if you can read you plants well. I use their chart as a Ratio, not ammounts, So if the chart says 5.0 FG, 5.0 FM and 10 FG, I just use the ration of 1,1,2. then work from that.
