Dark harvest grow challenge: RosettaStoned

[RosettaStoned]

I think they'll like the large space 😁 I was surprised at the OH roots. I was expecting a brown mess.

I recognize those gallon bags ,Do you slit the bags before you transplant them ?

 

[RosettaStoned]

I do not

 

[RosettaStoned]

Been busy...
they all seem to be ok. GC DWC seems to be a little slow still. Same with DGTH "OH" also a touch yellow overall. The pH drop was a fluke as suspected. Isn't really bothering the GC though. Started kelp tea foliar on the four organic. Dutch master saturater and liquid light with rhizotonic and A&B for the DWC.
how does everyone who uses a foliar brew their's? I still haven't tried to brew a compost or EWC brew/tea. I just soak kelp or alfalfa meal in water and use.

 

[Chefbjy]

I've done the same soakingin water. I'm going to get a compost brewer running though. But I went ahead and got some soluble kelp from dte. The compost brewer will save time when making teas breaking it down faster and keep the tea from going anaerobic. I use a homemade surfactant with soap and oil. They look great btw.

 

[RosettaStoned]

Thanks, I'm trying not to helicopter grow 😄 I should have cleared the schedule for this. My other plants are lacking attention and suffering for it....that and my stupidity

 

[Chefbjy]

I should have been done by now but my seeds weren't autos and I couldn't bare to cull them. Only in 2 stages same organic grow now so it won't be so bad 😉.

 

[oldjarhead100]

I have only been using them for a short while and have not finished a grow so I'm curious about how the roots grow though them , I don't see a problem but still its something to worry about lol

 

[oldjarhead100]

I made one of the ventorie tea brewers works great and it oxygenates the tea as well was easy to do I believe Campesino posted the pictures

 

[RosettaStoned]

DWC- 8/31 bucket change, 4 ml silica, 15 ml calmag, 15 ml cannazym, 15 ml rhizotonic, 10 ml A&B Vega, 3 gallons water. 1260 EC 6.0 pH been able to keep the water temp on an average of about 68-69. Roots have finally started to explode, they definitely do not like the frozen bottles banging around. Checked today and added 1 ml pH down.

GC ☝️☝️....................................DGTH ☝️☝️

Soil- 8/30 no water, have been getting daily foliar with a light kelp spray, 8/31 32 oz molasses water

"OH"- have been struggling to get this pH down, if anything it's going up. GC still looks great, DGTH slowly moving along and still a few shades lighter than the rest. Consistently 12 oz in about 5 oz out for each, every day. Recipe is the same as 8/28 but making half. Addition is mammoth p at .25 ml a half gallon. Going to bump it up next batch I make.

Off with their heads tomorrow night, going to shoot for leaving four nodes on all. Might wait to get them all there or just take what I get.
Thanks for stopping by ✌🤘

 

[RosettaStoned]

Oh yeah, DWC recipe will continue the same until flip. Maybe some slight adjustments in nutes if needed.

 

[RosettaStoned]

Soil- 9/2 32 oz plain water, outer edge to half way in. Foliar kelp spray and stuck in ring for training. Rotated pots, raised the light 2"
9/3 topped with 1 Tbsp bat guano (high N), 1 Tbsp neem cake, 2 Tbsp fish meal, worked into top 2".

DWC- 9/2 removed 32 oz, replaced with RO to dilute DGTH. Had a few clawing tips.
9/3 foliar spray, Dutch master saturater and liquid light with canna nutes/additives. Added some RO water (for now) to bring the water level up. 3 drops of pH down, down to 5.9. DGTH has that minor deficiency.
Been keeping the pH between 5.9 and 6.3 on both and still keeping up with the "cooling system" 😄

Raised light 2" 👇☝️

"OH"- 9/2 Transplanted into 5 gallon pots. There were roots on most sides and coming out the bottom of the medium on both. DGTH was a little more fragile but they powered through it without issue. Looks like a shade or two more green as well. GC still not batting an eye. Mixed nutes 2 tsp trinity, 1 tsp B grow, calmag, bio root, 1 ml mammoth p. Watered with 64 oz each, both about 7 oz run off. 4.24 pH in GC 6.16 out DGTH 6.1 out.
9/3 made half the solution, 1/2 tsp trinity. Each got 32 oz to see were I stand on runoff. 16 oz each but pH in was 4.15 in and 6.69 GC out DGTH 6.6 out. I was expecting it to be right back up there. So the question is do I continue to have that much run off or use less solution to get less run off? Topped with 1 Tbsp kelp meal and my fertilizer mix, worked into top 2" to soak for tomorrow's watering. Both are looking good, DGTH has slight yellow tips on a few leaves.

9/2 all got topped at the fourth node

GC

DGTH

alfalfa meal tea, 1 tsp 16 oz - kelp meal, compost tea 1 Tbsp each 16 oz water
week 5, GOO

a reminder the more exciting part is coming up faster than we think.
Also, hopefully these are close to done by then..... doubtful though. Otherwise the flower room will become one continuous beam of light with a lot of plants in it.

That's crazy!! I'm sure the buffers are keeping it adjusted but wondering what's going to happen when are eventually leached out. How often are you watering "oh" ? Since its mostly coco are you letting any run off wick back up? Curious with what fertigation you're using and the organics in the medium are doing.

I don't think down is organic or the added nutes. I'm sure you'll be fine and are prepared to handle more frequent fertigation with solutions. I just think with an organic medium you shouldn't add non organic nutrition. The organic microbes will fight for their lives if your adding non organic nutrition. But hey they look freaking great 👍. Looks like you're well ahead of me now 😉.

 

[RosettaStoned]

Chefbjy I water them everyday. I run off and drain only because I want to check the pH. I've thought about not running off or draining. My down in earth juice natural down, 99 9% citric acid. All the nutes and additives are certified organic. I'm treating it like coco but with organic nutes, or trying to.

 

[Chefbjy]

Sounds good. Glad you have certified organics 😃. Being organic will definitely throw off ec but wondering if you can fertigate more frequent due to it being coco. I wouldn't try to over water but maybe something I'll try down the road.

Campesino the site looks great and this might be an intresting topic to cover. Let's not overlook the power of organics in a medium like coco. These girls look great and I'm rooting...no pun intended for RosettaStoned oh mix 😉.

 

[RosettaStoned]

I don't even check EC. I just use the root organics bottle's recommended dose and cut it down. Same with general organics bottles. They seem to be fine with where they are at, trying not to push it too much. There is the amendments in the soil too. I have been pushing up the humic acid.
If I didn't have the pH to worry about this mix/nute line isn't bad for a first try. For sure needs some refining. Definitely will look over the recipe and omit the buffers next time. I kinda want to leave the bio char in because it helps with drainage, gives a place for microbes to live, and suppose to increase CEC. I read somewhere pH is determined by what is used, duh, but also the temperature that it is burned and cooled. Something to do with oxygen exchange.

 

[RosettaStoned]

Everything is looking good, other than the two DGTH leaves which could be damaged roots, pH swings, or nute burn from the foliar. They seem to be moving right along now. Daily fulvic acid sprays with weekly waterings added in. It says you can so I asked them, but you can use it in DWC as well. So I put in 1/4 tsp in each res to see how it goes. Normal dilution is 1/4 tsp per gallon.

the cooling device is working better than expected now that I switched out the bucket for a cooler. Between 64-66 degrees with ice pack changes every 8-12 hours.

the pH seems to be staying below 7 in the "organic hydro" mix. I have been still watering with 4.5ish pH solution but gradually trying to bring it up. DGTH has given up being sad with the mix and is taking off. Still using 32 but gradually getting less run off.

Both soil are getting top dressed weekly with high N guano, langbeinite, and rock phosphate. Alfalfa teas and kelp and compost brews. "OH" is getting guano, neem cake, and azomite. Anything else gets watered in with the solution.

 

[RosettaStoned]

Campesino I agree on the pH but I knew that to start. I can't really monitor EC because organics are not salts. At least that's what I was told. The readings can be way off.

 

[Chefbjy]

Looking great!! You'll probably be taking those leaves off anyway?? Wish I had gotten the right seeds 😢. I'm going to do things a little different next time around.

 

[RosettaStoned]

Yeah, I'll take them off sooner than later. Yes it's a bummer on those seeds, I can't believe it really. What kinda program are they running over there?
What are you going to do different?
