40+ lbs with 12 Plants in 2 Rooms on a Flip

[New Age United]

These started 12/12 on 12/11/18 so they are about 23 days into flowering. Another 47ish to go.

Strain is Gorilla Glue #4. With this strain I manage 42 to 48 pounds.

Each row that has the galvanized trellis rig have 2 plants. 6 plants per room, 2 rooms on a flip. Each room has 9600 watts of lighting. 6000 DE overhead and 2400w vertical end row lights with batwings plus I use and 2 x 600 watt verticals between rows. The side lighting is on a high temperature cutoff in the rare event things get too hot.

My plants are in black 10 gallon buckets. The 2 oddball plants in the rolling white 5 gallon buckets are my girlfriends plants.

All buckets are top feed drain to waste (bucket in bucket with hose to floor drain). I use Berger BM6 HP medium. I cut my clones from plants about 14-20 days into 12/12 so as to improve branching. Once rooted and transplanted into 10 gallon buckets my plants veg for about 40 days from clone in a dedicated veg room and are then moved into the flowering rooms after a harvest and cleanup. Then they are vegged another 10-14 days to get them trellised out sideways to maximize canopy area, create more bud stalks and keep it even as possible.

Feed is General Hydroponics Flora 3 part with Armor Si and Calimagic. I also add Advanced Nutrients B52 and Age Old Mycorrhizae (dry) and Advanced Nutrients Carboload to feed those microbes. pH 6.3 to 6.7 using Advanced pH up and down.

Each room has a 4 ton ceiling mount minisplits (also on the flip with the lights), natural gas CO2 generators, autopilot controllers, swamp coolers to add humidity when required and dehumidifiers to keep it from getting to high (not a problem often here in this dry climate). RO filter provides clean H2O.

For scale purposes the galvanized pipe trellis rigs are 5 feet tall from the floor, 4 feet wide and 8 feet long.

Subbed, you're crazy man.

Cant wait to see those monster again before harvest @mmmmmmmm

Looks great,any special feeding these last two weeks?

Just tapering off the PPM is all. No PK boosters of anything.

Do you "flush"?

or just taper gradually right down to harvest?

What ppm was your max in flower?

Day 66 update:



Bud close up of a side nug, some leaf tip burn from early flower, my girl accidentally used the wrong tank mix chart for a 55 gallon tank instead of the 30 gallon tank. lol



My girls Star Dawg plant. Probably coming down in a day or two.



Here is my nutrient mix chart from this run.

See the chart in my previous post. Max PPM is about 1260. I don't flush, I just reduce the nitrogen.

lol god that room looks ridiculous

nice job man, you obviously got your shit dialed in.

So if your max is 1260, just how much tapering will you do, what will your ppm be on your last feeding roughly?

Sorry for silly questions, i am about to enter into the last couple weeks of my first harvest and am preparing to do the same as you, taper down ppm and not flush.

Thanks man. I hope that others can benefit from my sharing information! I have learned a lot from others over the years and like to share what I know. I am far from a perfect grower but I sure love doing it. Always learning, never stop learning. The minute you think you know it all you stop learning.

Ill have to get a reading on my next tank mix, they are refilling off the RO filter presently.

I firmly reject the idea of flushing, I feel the plants need to eat when finishing (the most important work they will do IMO). I just reduce the nitrogen at the end because thats what makes for dark green sparkler buds.

Perfect grower or not, you know how to grow and have extensive knowledge that can help so many newbs and vets alike.

Its just refreshing to see guys like you who are willing to help , thats the value of a place like this.

Trust me, people are benefiting, atleast i know i am lol

I am only using the 1 part floranova bloom. 4-8-7, used amor si up until last week. no other additives.

will i achieve a similar result by just decreasing ppm, which in turn will be reducing N in the process

I am not familiar with the Nova line. I don't like to reduce the PPM on the P and K too much just the N. If your plants are light green and you are getting the yellowing and dying of the fan leaves from the bottom up then you not overdoing the nitrogen. When I see plants that are near done and all the fan leaves are still green thats a sign there was too much nitrogen.

I guess this is where using more than 1 part nutes comes in handy. In order for me to reduce N i obvously have to reduce P and K ,which we dont want to do.

I have 1 plant that had some issues, I think it was related to PH, her older leaves look rough but all her new growth looks good. She is also the darkest green of the 4.

The other 3 are doing as you say, kinda lightening up from the bottom up

This is the problem child below

How long has that plant been in 12/12?

 

[diggs99]

38 days since I flipped

Here's a pic of her buds

She is def further behind than her 2 sisters

Issues started last week. One day one yellow leaf, 2 days later, pic above. Hasn't gotten any worse since then but looks ugly lol

It looks to me like you may be a little phosphorous deficient. A nitrogen deficiency will start at the very bottom of your plant and the whole leaf will get pale then yellow then brown and dead. Looks like there is a lot of nitrogen available because the leaves are dark green. I personally dont want to see that much nitrogen in flower. Looks like you have a ways to go in flower so there is some time to correct that should you choose to do so.

I personally want to see the plants looking rather crappy (fan leaves) in late flower. They should be consuming mobile nitrogen from the fan leaves and at the end the plants buds are the only thing that look good, the rest of the fan leaves are looking like shit. But thats just my way. I always get really good bud that smokes great when dry, no cure or flush. P and K are important in the end. The P = yield IMO and the K = terpene production. With the three part nutes I can manage the numbers well and dont need a PK booster.

That makes total sense, ive seen many grows, all the best looking bud never have nice leaves before they harvest lol

I watched a video that looked very similar to my issue and it was Phosphorous deficient. I was told to flush the plant with ph`d water and then refeed. I honestly dont know if this was correct to do or not lol

The other 3 are much lighter and have leaves doing as you say, yellowing and dying off from the bottom up, but this one has been darker green this past couple weeks and now the leaves going all nuts.

I think i will be moving to a 3 part nute going forward, if for no other reason that what we are discussing right now. Seems you have more flexibility when it comes to tweaking things as you need it.

Phosphorous can build up in the soil and lock itself out. A flush is a good way to get the excess P out of the soil.

My flush method for fixing salt buildups mid run.

Mix RO water with a little epsom salt to get about 100PPM. Plain RO water will suck the life out of your roots. pH to 6.5. Then I water with enough to fully saturate the soil and see just a little runoff. Let it sit for 20 minutes to allow the water to adsorb the salts in the soil. Then I water again with just as much as the first time, you will get a lot of runoff, runoff should be about the amount you just added. Check that for PPM, it should be high indicating that it has pulled salts out of the soil. Next I FEED. Don't wait to feed after the flush or the plants will get pissed.

I personally like to do this every 2 weeks or so during flower to prevent any buildups. Just remember, never use straight RO water and FEED after the flush. Over watering isn't what you just did, it's not letting the soil dry out between waterings thus lack of dissolved oxygen and suffocating the roots. The flush then feed only counts as one watering because it's all done pretty much at the same time.
