So we are getting to the end of week 4 of Veg in the Recirculating Deep Water 💦 Culture buckets and I have just completed a complete nutrient change out. I refilled the system with nutrients mixed at 40% of the recommended strength. My recipe for week 4 of Veg is as follows:
Jacks Hydroponic 5-12-26: 6 grams per 5 gallons
Jacks Calcium Nitrate 15-0-0: 3.6 grams per 5 gallons
Terpinator: 25 ml per 5 gallons
Hydroguard: 10 ml per 5 gallons
Orca: 2.5 ml per 5 gallons
Rapid Start: 5 ml per 5 gallons
When mixed the solution comes at 480 PPM on the 500 scale.
Plants are absolutely loving the formula, and I’m not showing any signs of nutrient deficiencies or overfertilization. Using the jacks is made nutrients change outs mixing in general it breeze using the Jack’s nutrients change outs & mixing in general a breeze. The Plus shipped modified manifold is growing exactly the way that I had intended it to. Each of the plants has been growing horizontally and beginning to fill out an even canopy as was intended with the way I tied down the branches.
I accidentally broke one of the main arms on the Gorilla 🦍 Bomb 💣, however, due to the fact that there was some skin still connecting the arm I was able to tape the arm back to the man stalk of the plant with electrical tape. 7 days later the tape was removed in the plant had formed a large knuckles where the brake had been. Love the resiliency of the cannabis plant, as losing that ranch probably would have cut down my yield on that one plant by about 30%. Check out how they look 👀 as I post bi-weekly videos to my YouTube channel:

@Nutria, my best highest yield for this setup was 37.25 oz’s. I’ve learned a lot since then, so provided I don’t have any unexpected wacky ness I think 🤔 I’ll hit that nunber. My largest yield was with 3 plants in the room, so with 5 as long as they are not overcrowded I am pretty confident.
@MagicMikesMeds, 40oz are achievable, 1.5gr/w is a common result with this kind of leds. If you look at the emitted spectrum you can notice a lack of IR wavelenght (≥700nm) in white leds, thus it is suggested to run higher temps than you would usually do under hps for example. Follow a VPD chart with a ±1c temp difference between air temperature and leaf temp.
@Nutria, this is my 3rd round growing under the Timber Grow Light COB LeD fixture so I am more than aware of its excellence. My goal for the 5x5 room is 40 oz’s, and I should have the perfect room temps to make a run at that number...
@MagicMikesMeds, exactly! I do the same and am constantly tweaking or trying something new every cycle just to track a new data point. @Dudegrowsweed just rec’d a book on his diary which I just read called marijuana cultivation reconsidered. If you like the plant science end of things it’s a great and layman’s terms informative read👍. Glad to see someone taking the defo into late flower - it’s a reassuring👊 Cheers😎
@TheBudWhisperer,I can understand your concerns about the late Flower defoliation, however, there is still significant leaf material intertwined in the buds to perform photosynthesis. I’ve noticed that the buds that have direct exposure to light have the best growth and development. By getting the light down further into the canopy through defoliation I get much lower bud development then you would had you left the heavy coverage of fan leaves. Controversial yes, however, my best run weight wise was one in which I religiously defoliated my plants every 4 days from the start of flower through to flush....people argued with me that the method was only hurting my yields, however, the numbers just don’t lie. I believe in data and vigorously track the data from my grows to see what works best for me in my garden. It’s science !!!
@Eauderay,the 2 different gorilla 🦍 genetics (Gorilla Bomb & Royal Gorilla) are both starting to throw out new pink/purple calyx’s. At first I thought that all of my plants were herming, due to the fact that it looked like nanners at 1st, but as they started to develop I could tell they were new calyx’s that we’re expanding the buds. 2 of the 5 plants are roughly 6 feet tall at their highest with the other 3 ranging from 3-5 feet. This weekend should be the final defoliation as I will be completing week 6 this week and that puts me at 42 days. Should be the final defoliation and that will leave roughly 4 weeks to fatten up ( I like taking my plants to full term - 70 days for these strains...

@TheBudWhisperer,yeah it came down 2 weeks early and I have already dried all of it. I trimmed half and then just ripped the other half from the stalks to dry. I’ll run the plant through the bubble washer in a couple of weeks so in the end I’ll just have lost a little weight in trichomes. Oh well, it happens to the best of us...
@Stress_Bud,I was going to start to flower them but I noticed a Calcium deficiency popping up, so I’m gonna do a full res change out and give them another week to eliminate the deficiency
I couldn't help noticing that you've placed lots of sticky traps. If you actually have pest problem, allow me to suggest you adding diatomaceous earth combined with propolis and pyrethrum. If rapeseed is in the mix it gets even better. This totally exterminates pretty much everything that flies or crawls. Peace
@vovaTHEKUSHMASTER, the sticky traps are strictly preventative. Last round I noticed an uptick in fungus gnats in my garden mainly due to the fact that my geographic location is loaded with them and it was the right time of year.
My medium is Growstone GS1 and is pure hydro, so adding diatomaceous earth gets really messy. I have found that covering my medium with aluminum foil and placing the yellow sticky traps next to the main stalk of the plant prevents the gnats from getting into my medium and eating my roots. So far this round, there are a few gnats on the traps, but I don’t see any flying in the room so it seems that they are achieving my desired results...
