First Time Grower - overcoming mistakes

[TomDaDon90]

I see how much lst training gets them a lot more bushy.

[Wayzee]

Yea that and I am lucky to have a se7000 spider farmer led, which is around 700watts so that helps stopping them from stretching...
Pretty sure that strain was Dr trichomes gelato..

[TomDaDon90]

So your pretty much saying to cut all the big leaves and cut them down to the stem below the yellow line in the picture you did for me??
That makes sense...!

[TomDaDon90]

Pretty much cut all the leaves that are below the yellow line that aren't generating any buds....

[Wayzee]

All the growth below those lines even it it has little buds starting to form....

[Wayzee]

ductwizard Yea man just for helping keeping it flat, it's what I had laying around so that why I used wire instead of a net... I haven't had anything big enough indoor to have to support branches... Yet 🤞🏾 haha

[TomDaDon90]

That's pretty cool, using wire instead of net bro....!

[Wayzee]

My whole room I made as cheap as I could out of old timber pallets, old iron roof sheets, old mattress Toppers and polystyrene foam for insulation and a few rolls of self adhesive gloss white wall paper off of Temu..

[TomDaDon90]

Okay and in the morning I will trim all the leafs and stems under the yellow line. The light will get to it much better. And thanks.

[TomDaDon90]

But you got one big as fuck led light that's kinda expensive lol with cheap as hell grow room and shit lol

[Wayzee]

Haha yea, I figure the most important thing is light.

[Rootsruler]

TomDaDon90 What you're doing by trimming some of the lower branches is concentrating more energy towards the top of the plant that get the maximum amount of light energy. Similar to topping a plant where you are redirecting the energy that plant has to where you want it to be directed. The plant naturally exhibits Apical Dominance which is what makes it grow like a Christmas tree. When you top it you are redistributing that energy to other lateral branches.

When I set my ScrOG net I don't weave the branches. I use the net to keep the branches spread out so that the entire canopy gets the same amount of light energy. Basically the net is there to hold the branch in place. Weaving it will lock that branch in and will not allow you to be able to readjust it if needed so I use the net to hold the branches down but they aren't tied to anything. The splayed branches receiving equal light will produce similarly sized flower from the base to the tip versus the traditional grow where the top bud is the largest and the lateral branches have smaller buds as you go down the plant.

This was how my last grow turned out using this method. As you can see the branches are held back from growing vertically and the flower sites are allowed to go vertical.

[Wayzee]

I notice the extender on your humidifier? Is that how it is or have you set it up like that so the humid air settles on the canopy,?

[Rootsruler]

Drphil69 - Thanks! I just watered them. They did all the work! LOL!

Wayzee - The extender was a DIY project I pieced together at the local Home Depot. The humidifier was too short so I rigged up the extender to clear the canopy. I probably could have made it shorter but I'm lazy and it worked! Hahaha!

[Wayzee]

Ok, haha if it working don't f#$k with it..... ☺️

I switched to 12/12 one month ago today. Here are some photos to show how the plants are doing now. I think the flower growth looks pretty good and can't wait to watch them develop bigger and denser over the next month. Still dealing with considerable yellowing. Reduced lighting to 75% (VivoSun grow guidance for the early flowering stage) and increased the nutrients (forum feedback). Did some defoliation last week so those inner and lower buds get some light and air.

[apacin0]

Bored and can't sleep. I did the math and at 18" above the plants at 100% power the DLI would be at 46.27 with a Vivosun VS2000. I looked it up and optimal DLI for ganja is 30-45 during flower, but can go up 50 or more.

[Sperocles]

Thanks, apacin0. I have been using both methods to defoliate. If the leaf doesn't detach easily by hand, then I will use the shears. I had a bottle of CalMag on order and was notified yesterday that delivery can't be fulfilled. Now I need to place another order and wait. I was trying to stick with all Fox Farm nutes but if I can't get their CalMag, I assume there won't be an issue if I mix nutes from different makers. I pH my fresh water and my nute mix to 6.5 every time before giving to the plants. Room temps where the tent is located are usually about 5-7 degrees cooler than inside the tent with lights on. I'm working towards adding a window A/C unit to cool that room more but don't think that will happen before harvest time for this grow. I do plan to go back to 100% intensity on the light VivoSun grow guidance says this for "late flowering stage". I just need to figure out what is considered late flowering stage. I'll have to do some research on the DLI stuff. If you don't mind doing more calculations, what is the DLI for VS2000 at 75% and 18" above canopy? Bluey, right now they are getting the following nutes (usually every other feeding/watering, but to give them more as someone suggested I gave the two that are most yellow nutes twice this week): Fox Farm - 1.5tsp/gal Big Bloom, 1tsp/gal Grow Big, and 0.5tsp/gal Tiger Bloom.

[apacin0]

Any calmag supplement will really work. You could also add egg shells and epsom salt, if you want to go more organic. I do liquid nutes, so no personal experience with the organic approach.

I calculated the DLI for 75% at 18" height and it comes to 34.70. (I posted the calculation for 16" height in a post below, which should also be safe at 75% power) This is actually within a good range for the early stage. I'm honestly learning more as I'm researching for you haha. Also note these are only calculation based on what the manufacturer claims the PPFD output is. They claim at 100% power at 12" height it outputs 1797 µmol/m²/s, at 16" 1300 µmol/m²/s, and at 18" 1071 µmol/m²/s. To approximate 75% power you just take that PPFD number and times it by .75. I was using this website to calculate the DLI.

Also when I originally suggested you use 100% I thought you had the smaller 100W unit.

[Bluey]

I think heats your problem. That light shouldn't cause light burn at any sensible height. Are you giving them bloom nutes? pH 6.5 to 6.8?

[Rootsruler]

apacin0

That high a DLI is if you are supplementing with CO2.

[apacin0]

Ah... I just read that if you're pushing a PPFD of over 1000 µmol/m²/s in a 12 hour period, you'll hit over the recommended threshold (without supplemental CO2) of 30-45 DLI. That being said, I think using the math at 16" height the Vivosun VS2000 puts out approximately 1300 µmol/m²/s, times that by .75 (which gets 75% power) you get 975 µmol/m²/s. Calculate that into DLI for 12 hour period and you get a DLI of 42.12, which is in the safe zone.

[TomDaDon90]

I have a question.
Okay I have a Cinderella 99 flower and Hollywood OG.
And they are both on day 9 of flower.
And the Cinderella 99 has like white hairs and some amber colored ones. And the Hollywood OG has only white.
I was reading that the Hollywood OG, since it's a OG it needs magnesium and calcium? I am wondering can someone show me where to find this online so I can read about...
And the amber color on my Cinderella 99 is that normal at day 9 of flower?

[TomDaDon90]

Nevermind I am using Happy Frog soil.
And my clone was in a wool like cube from Good source grower.
And I just found out my soil has magnesium in it and lime something.
So I really do not need any food.
And my Hollywood OG does not have a magnesium deficiency.
It's leaves are perfect. So I must be doing something Right.

[Bluey]

Over 1000 PPFD on the canopy (the leaves) will cause issues without CO², the leaves will probably die back quickly.

Edit. I thought you were only using a little 100W light also.

[TomDaDon90]

I have a question.
They have baby clones at my MJ dispensary.
And I have my flowers on 12/12hr now and I'm wondering if I can buy this baby clones and keep under 12hr light until May 25th, because after then the weather will stop raining and be warm. And I can plant it outside until October with happy frog soil I have. I'm just wondering can I keep a baby clones under my MJ flowers in flowering time until May 25th. That's about 7 days?

[Bluey]

7 days may be enough to flip it into flower then you'll spend many many weeks working to reverse that so you can re-veg it.

[Rootsruler]

Can you place them somewhere where you can supply supplemental lighting? I would also talk to your dispo and find out who the breeder is. Maybe you can be in contact with them and when you are ready they can provide fresh cuts.
