Following H3ad's Formula (1000W - 5 plants)

[Critter]

Your getting good results so i dont say this meaning you should do it, just sharing my experience. I used to run 6/9 like you i drop micro, but then i cant even remember when but iread some things and decided to run strickly 6/9 till last 10 days to a week or so ,,,then drop 6/9 by increments example, 4 gal of tap with 3 gal ratio worth of nutes and last 3 days or so just with tap water and heavy 16 Finish. I found the end product more aromatic, healthier at finish and more rounded stone. All subjective of course

Looking good.

I'm strictly on 6/9 as well now. Dropped the calmag, things are looking really good. I'll probably run 6/9 until final flush.

I also set up an auto watering system which is working great. Watering 3xs a day and they look healthier than ever.

1 month 12/12

Yep, that's the magic formula. The calmag was doing me no good.
My Purple Kush was 35 inches tall, one top, 1 1/2 mo. bud and yielded 4 OZ dry. I went the final 10 days or so straight water flush, after a few weeks of 3/9.

Next up is a White Queen, it has maybe 2 more weeks till harvest.
Same thing with it- 6/9 since birth. This time, though, I'm going to go 6/9 right up to the day of harvest. I know people will tell me otherwise, but I need to find out for myself.

I know multiple small feedings are the way to go... Unfortunately, I'm lazy, and I end up just doing one big feed a day on the big plants and maybe two on smaller plants that are thriving.

I learned that coco is not easy to get out of roots. I think next time I harvest, I'm going to fill a big tote halfway with PH'd water, then just swirl the root mass gently until it all breaks up... Gonna try, anyway.

BTW- Your plants look great!

Hey bud, any close ups on ur pk?
6/9 all the way thru will work fine. Make sure u get some runoff though, so u don't build up nutrient in ur medium at the end of harvest that will effect taste. I've ran it with great success, but now I cut out nutes the last 10 days or so, and just top my res with water only.

Try soaking ur used coir in pond enzymes. It will eat up all the roots for u.

I havent taken any good pics of my plants or buds yet because my super-expensive Nikon can't take a good still image to save it's life. Plus I run sodium exclusively in my main grow room and that's always a bitch to take a good photo in.
I don't know how those guys get such good shots under sodium.. I use everything I can in Photoshop and still have lousy results.

Using the camera's flash with a fast shutter speed (200) helps a bit.

Nice update bud! If u have the same Pk cut I have, try letting it go 65 to 70 days next run. It's ultra potent that way. It's the only hash oil I have ran that's reached 90% cannabinoids. Can't wait to hear a little smoke report on the Marionberry. I ran a pack and was real intrigued by it, but never got to finish the grow. It looked like it was dipped in trich's though.

Where's them pretty pics bud? I just turn the hid's off now use a regular room light or shop light to take my pics. Right before the lights come on or after they go off is fine. Doesn't cause any problems with the flower cycle.

I wouldn't say 8/16 is superior... but I can imagine the plants would like it weeks 3-5 during flowering. Otherwise, its out of balance. I personally down the micro/nitrogen to 4, and up flower to 10, then add some PK, floralicous, etc for a couple weeks. I will eventually cut the micro completely the last 2 weeks.

[Sampson0420]

8/16 is superior, I've found that much out. As for adding anything extra, the cottage industry appreciates your support.

Ok, good to know, just to be clear, are you suggesting people go straight lucas and do 5/10 veg, 8/16 flower, or are you saying do 8/16 from start to finish?

Straight lucas isn't 5/10, it's 6/9.

 

[Sampson0420]

Straight lucas isn't 5/10, it's 6/9.

I apologize, I thought Lucas was created for hydro using 5/10 veg, 8/16 flower. The 6/9 ratio on the other hand, is used for both veg & flower and was created by h3ad for coco... no?

Lucas Formula - A Hydroponic, soil, and coco Feeding Regimen
Please direct all Cannabis related questions to http://askcannabis.com
Summary:
Lucas Formula, sometimes known as the Lucas Ratio, is less complicated than it initially seems. It is nothing more than a basic recipe of nutrients to give your plants during both the vegetative, and the flowering state.
The original recipe uses 2 parts of the General Hydroponics 3-part FLORA series (Gro, Micro, Bloom) nutrient system, but Lucas Formula may also be used with Advanced Nutrients, GH's dry nutes (Maxibloom), etc.

Lucas Formula using General Hydroponics 3-Part System
General Hydroponics makes a 3-part system named the FLORA series. It consists of FLORA GRO, FLORA MICRO, and FLORA BLOOM. These are 3 bottles you buy, that you would normally use together throughout the entire grow. You may use it as per the instructions on the bottle, with excellent results, but...
Lucas figured out that FLORA MICRO contains enough nitrogen, and everything else that MICRO GRO contains, that you use it with FLORA BLOOM alone, saving you from having to buy FLORA GRO.
How do you use it? Simple. Add 8ml of Flora Micro (dark red stuff) to 1 gallon of water*, mix, and then add 16ml of Flora Bloom (pink stuff) into the water, and mix. Done - unless you're growing in coco. If so, see below.'


Lucas Formula using General Hydroponics Dry Nutrients (Maxibloom)
MaxiBloom and MaxiGro are dry nutrient also from General Hydroponics. It turns out, Maxibloom, used in a ratio of 7 grams per gallon of water*, is very close to the original Lucas Formula (above.) You do not need MaxiGro, and so this is the cheapest and easiest recipe to use.
Add 7 grams of Maxibloom into 1 gallon of water*, and then adjust the pH, and stir vigorously to dissolve the Maxibloom in the water. I advise putting the 7g of Maxibloom into a cup of warm water, dissolving it, and then adding it to the remaining gallon of water, before pH adjusting and mixing again.



Lucas Formula using General Hydroponics FloraNova series
This is probably the easiest (but not cheapest - see MaxiBloom above) feeding plan available. If you're using General Hydroponics' FloraNova Bloom 1-part system, simply add 8ml of FloraNova per gallon of water* and feed.


Lucas Formula when growing in Coco Coir - Head's Formula
If you're growing in coco, you may need to adjust the Lucas formula slightly to compensate for a property of coco which may result in a calcium or magnesium deficiency. How? You may be able to get by simply by adding 1-2ml of calmag (or MagiCal+), or 1 gram of Epsom salt (any pharmacy carries this), per gallon of water, before feeding the plants.
There is a modified formula specifically for Coco that consists of using a different ratio: 6ml of Flora Micro, and 9ml of Flora Bloom, per gallon of water, along with 1 gram of Epsom salt per water.
Either works, but be sure to try Head's Formula if you're having deficiencies or other nute/pH problems.
If you are confused or unsure, ask your Weed related questions here!


Low light ratio, and flowering vs veg
Lucas Formula should be used in the same ratio throughout the grow. There is a misconception that one should use 5ml of Micro and 10ml of Bloom, when in veg, and switch to 8ml of Micro, and 16ml of Bloom, when flowering.
This was never stated by Lucas himself. He originally stated that the 0-5-10 ratio was for LOW LIGHT situations (fluorescent lighting like PL/L and CFLs, or HID lamps less than 400W), whereas 0-8-16 is for medium to high light (400W+)


* What type of water should I use? What about pH/ppm?
The original formula uses reverse osmosis, or RO, water, and is intended to be used without having to measure pH and ppm. Reverse Osmosis water makes this possible because it should, in theory, be the same for everyone. It is filtered water, which you can get either by buying a reverse osmosis filter system, or just buying bottled water (among other brands, Dasani, the bottled tap water is reverse osmosis, for example). One may also use dH2O (distilled water) with good results. You can get distilled water from most convenience stores (Walgreens, CSV, Rite-Aide, etc..)

Lucas Formula for seedlings/cuttings
For young plants (< 4 weeks old) or cuttings, which may not be able to handle a full strength feeding formula, may require that you dilute the nutrient solution before feeding. This is OK, just make sure you keep the correct ratio when mixing. For example, 50% strength would be 4ml Micro and 8ml Bloom, or 3.5g of dry Maxibloom per gallon.
Lucas Formula with tap water
You may use Lucas Formula with tap water successfully, but this may require pH adjusting on your part. Keep the pH close to 5.8.

Can I use additives with Lucas Formula?
You may. It is recommended that you do not introduce additives until your setup is dialed in. After you've ironed out any deficiencies and fully understand how your plant and strain likes to be fed, feel free to begin using additives (such as Floralicious) - not that the additives will help. For increased quality and yield, focus on good genetics, and ample light and temperature control, rather than trying to compensate for those with additives.
