How to pull max weight and Quality for OG Kush.
You must have the proper light intensity with the right canopy structure & plant height. You must create a completely sealed controllable environment that controls temperature, humidity and air flow & that is enriched with the proper CO2 levels at the right temperatures. Nutrients are secondary to the above. If you don't have the above dialed in, the your nutrients will not work to their full potential.
Use a strong AC unit for complete control. This is a 5 ton I use for my 10 light
Gavita room.

Use a CO2 generator to produce CO2. I prefer this method over hauling in heavy CO2 tanks every week

Use dehumidifiers to control humidity and wall fans to move the air properly. Also use floor fans to move air in the bottom of the canopy. In the wild cannabis won't pay much attention to bud sites that get no proper air flow and light intensity

Use a charcoal filter from the top to remove extra humidity and heat from and to scrub your air once or twice during day cycle.

Use tables with rollers to easily get in to your canopy and make sure to collect the runoff under each table to make sure that ppm and ph are optimal for the week of your flowering cycle. Weeks 1-2 aim for run off ph 6.0-6.4 for nitrogen needed for expansive growth. Weeks 3-4 aim for 5.8-6.0 run off ph to make sure that they get the necessary phosphorus to develop more bud sites. After that you can keep runoff around 6.0 - 6.2. I usually aim for 5.5 ph when mixing my nutes to balance out the rockwool. Sometimes you may need to go a little lower to bring down ph.

Aim to create an even canopy structure, especially when using
Gavita lights. When I first used them, I under estimated their power and placed them to close to my tops which caused my buds to get light burn and fox tail. Keep them around 40-42 inches from the tops. For Digital ballast with
hortilux bulbs I usually keep them between 18-24 inches from the top of canopy. Preferably closer to 18 if your plants can manage the heat.

Setup:
Digital ballast:
You need a complete sealed environment with CO2 enrichment to pull 1 gram per watt using 1000 watt digital ballasts with HPS
hortilux bulbs. Use a 4x4 foot area (16 aquare feet) for each light and use 6-9 plants per light. I like to use 9 per light on a 3-4 week veg cycle. I usually top them twice (I use these cuts to make clones) to create more shoots and don't let your plants get over crowded during veg or else they will stretch. Veg with metal halide bulbs. Start them at 600 watts and then slowly get them to 1000 watts by middle of week 2.
Gavita setup:
Gavitas can nicely light a 24 square foot area per 1000 watts. This room above is a 10 light
Gavita Pro setup covering a 240 canopy square foot space. It would take 15 1000 watt digital ballasts to illuminate this same square footage. I do 2+ pounds per light using digital ballast. How do I pull 3+ pounds per light with Gavitas. Well do the math. If I'm covering the same area with 10
gavita lights that I would normally use 15 1000 watt digital ballast and get 2+ pounds per light (30 for 15 lights) Then with 10 gavitas I also pull 30 on the same square footage which makes my numbers go to 3+ pounds per 1000 watt
Gavita light.
When you bring them into your flowering room. I always flush the first day and then start with the week 1 mix on the second day. You can use a product like
Clearex to flush for this first time or you can use 100 ml of SBA/SBB to flush them as well. Flush them for like 30+ seconds to ensure they are clean for the next days mix.

This is my OG Kush Recipe above that we use in the SFV to grow OG kush. I've actually adjusted to lower ppm's during last 6 weeks to get the best quality. To get best results you must use Super Nutrients SBA and SBB to bring out the best out of OG kush. Most growers over feed OG kush thinking that its a big feeder. Maybe for the indica dominant OG kush types but for the sativa dominant OG kush, it requires much less nutrients than most people give it. When you over feed OG kush, your buds will turn out dark and not lime green like they are suppose to look. When it comes to nutes, remember that less is more.

Note: When recirculating do 10 seconds up one way then 10 seconds back the opposite way. This ensures that all your plants get an even ppm mix. I hand water my plants because I enjoy it and get the chance to give them that extra especial attention where I see needs. This is how I make sure that my OG kush buds sit as the top shelf buds for all the dispensaries that carry it.
Note: When you run to waste feed until you see 10-15% runoff
* When you recirculate and give them 20 secs total, this extra watering promotes rapid leaf development, the early use of monster bloom which has high phosphorous helps create more bud sites.
* You can stop recirculating earlier when you feel that your canopy has filled in nicely to your grow space. If you keep recirculating past this point you will get too many leaves which will shade bottom nugs too much and you will have a tough time defoliating all the extra water leaves
*If some shoots start stretching, pinch them by squeezing the stem to slow their growth down. The shoot will stop growing for a few days since the plant needs to repair itself which allows the other shoots to catch up.
*Use nets to build your canopy structure. The low net at 24 inches from the bottom of plant and the top net at 36 inches from the bottom of plant. Aim for plants to be 42 to 48 inches max in height. If most are at max height then add a third level of nets at 44 inches
* When you switch to run to waste and you feed for less time usually 10 seconds this helps rockwool dry up a little to promote flower production,
Big Bud which has more potassium helps bulk up your buds
*You need to defoliate the plant after it has finished its rapid growth expansion usually by week 3 because an indoor environment with co2 promotes many leaves that are not needed for flower production
* Never Defoliate a plant that is not healthy or has bugs or pest problems
*Defoliate a plant by removing water leaves to get your lux meter to read at least 5000 lux at all bottoms (No need to lolipop bottoms with this method)
*Your top canopy lux should be around 25,000 - 30,000 lux make sure you find the balance of your light height so that you don't light burn or heat burn your colas which will make them stop growing prematurely
*Regarding flushing. You must track your plants ppm runoff coming from the bottom of the rockwool cube. If the ppm runoff exceeds the nutrient runoff for 2 consecutive days then flush with 200 of cal mag and 100 of carbo load or
bud candy when using RO water.
*The goal of the 1st 4 weeks is to develop the proper canopy structure with minimal internode length stretch by keeping the ppm in and ppm runoff in balance. Meaning that the ppm in comes back the same as the ppm runoff. This is not an exact science when you follow a nutrient formula chart. Even with my formula, I need to make adjustments depending on the room and setup. Plants in the middle which receive the most intense light tend to use more nutrients than my tables on the edges near the wall. Use nutrient schedules as a guideline but rely on the ppm and ph run off numbers to plan your next feed. Sometimes I have to flush (Lower the nutrient ppm with cal mag and
bud candy or carbo load at low strengths like 250-300 ppm) The reason why I add extra sugars during my flushes is because I defoliate my plants which lowers their ability to produce their own sugars but by supplementing them with extra sugars I compensate for that and get more weight because I get more light to the bottom nugs.
*The goal of the last 6 weeks is to feed your og kush plants where the ppm runoff is slightly lower than the ppm in, this will create a small nutrient strength deficit which your plant will balance by taking it from their own leaf storage. This will make your leaves start to slowly turn lime green and by the end of the round your leaves should be a healthy yellow and not burnt. This technique takes some practice to get used too. If you get in trouble and start losing too many leaves you can foliar spray to help keep them alive. But make sure that you do not have powdery mildew. In fact if you have bugs and or pm then you will not achieve best results. It is normal to lose leaves by weeks 7-9 which helps further add light to those developing bottoms.
Summary:
*The key to pulling weight is light intensity coupled with the right environment with no bugs or PM. Nutrients are secondary to the above factors.
*You need to build a completely sealed environment where you can maintain the right Co2 levels with the right temperatures to get that extra growth. (Canopy temps should be between 82-88. Aim for 85 degrees farenheit
*Make sure you have proper air movement in your room from the top and bottom of the canopy. Use wall fans and floor fans to accomplish this.
*Humidity during flowering should be between 45-55 percent. Aim to have it 50%. Use dehumidifiers in a complete enclosed environment and a charcoal filter that can extract heat and humidity from your room from the ceiling if temps and humidity get too high because of a hot summer day
They key to getting best quality, taste and smell is to start bringing down your plants ppm by week 5 which is contrary to most flowering schedules. The last week flush is not enough to make your buds smell and taste better. You need to slowly bring them down making the leaves turn lime green to a healthy yellow in the end.
