Crawdaddy's Fall 2013 TopLED COB Grow

[Scarfinger68]

Phosphorus can lead to smaller plants/slow plant growth and your plants seem small compared to the pot size. But... you had good soil to start with. So there should have been plenty of nutrients in the soil.

My guess is...*thinking* It has to be more of a lock out? Low PH? But then again the hardcore soil guys will tell you that you don't have to worry about PH in soil. But... I always worry about PH and I grow in soil. hmmm. Maybe the air-pots didn't allow water to thoroughly saturate the soil and you developed some salt build up that lead to a lock out?

Hey Crawdad
Weederfull week to you

 

[b.real]

I would use only molasses from now until you see some normal yellowing going on.

 

[RainStacks]

Just stopping in to say hi. Sorry to see things are not going too well. What Scarfinger said made a lot of sense to me. Maybe flush one and see what happens?

 

[Crawdaddy]

What is the soil mix or why do you think it is bad? Or... anything different this grow besides maybe soil?

I think it looks like a phosphorus problem.

You are on a lot of the same ideas I am on. The 3:2 Mix of Fox Farm Happy Frog: Fox Farm Ocean forest I think is too low in pH locking out phosphorous. The problem is I did lots of things different with these 4 plants, big ass airpots, new soil mix, and new light. So it hard to rule out one.

When i made the soil and transplanted the plants I REALLY saturated the soil, but it could have dried out funny with the airpots.

For my next batch I am just going to use straight Pro Mix, with ferts when needed. Until I try Doc Bud's High Brix kit no soil with food in it for me. I am also going to use 5 gallon pots of both airpot type and regular nursery pots. In fact after my trip to Singapore next week, I may just sh*t can a couple of these plants and replace with some in 5 gallon pots and just Pro Mix.

Part of me is hoping it is the soil and not the lighting, the soil can be changed a lot easier.

Hey Crawdad
Weederfull week to you

Hey Chronic, same to you, only 2 day work week for me this week yee haw!

I would use only molasses from now until you see some normal yellowing going on.

Just using plain water. They already got their molasses, well maybe one more batch of it, but I have pretty much given up on these plants.

Just stopping in to say hi. Sorry to see things are not going too well. What Scarfinger said made a lot of sense to me. Maybe flush one and see what happens?

Its cool man, I just look at my 3 plants under the DS200 and I get happy again, they are doing well. Probably do update tonight. I would flush, But with 15 gallon pots and airpots makes it hard, plus i have pretty much given up on these plants, at best I will get an OZ of hopefully good smoke, but crappy looking buds. I have noticed the stressed out plants can make strong smoke, just not much of it, I think stress makes them produce more THC. The airpots are probably not good for flushing because if pour a lot of water the water just flows out holes in sides and does not soak in. Plus with 15 gallon pots would have to be a TON of water. I am going to save these pots for next outdoor season. Buying some 5 gallon ones for next batch of plants.

But hey with experimentation you are going to get failures.

To me you can rule out everything apart from the soil. Yet that said it could be a number of factors in the medium. Its really regrettable that your girls are in this way my friend. I would most certainly flush one and see how it reacts. Hope you get improvement soon.

 

[Graytail]

My two cents ...

I think you're right on the money about the soil - it's just too hot - and there isn't much you can do about it in the 15 gallon pots. The plants aren't large enough to take advantage of the nutes, or to dry the pots out enough to get adequate aeration. They would have been if the soil had been more welcoming, but they've struggled and remained too small for the pot. If you try to flush them now, you'll over-saturate the pots and also release more nutes - a no win. And now they're too old to even consider repotting.

The good news is that even though your yield will be disappointing, the buds that make it to the end soil should be all concentrated and pack a serious punch. I'd be trying to focus all the growth on the healthy tissue. Of course, the bigger the plant, the better able it is to handle the nutes and soil volume ...

Dunno ...

But Pro-Mix is the solution, yep. You can take it any direction from there.

I think it really is too late to turn these ladies around, I have pretty much already chalked it up as bad experiment. Thankfully I have many jars left of my out door.

Yep that about my analysis of the soil situation, to late to do anything worthwhile. But I have clones off all these plants so not losing the genetics. If i was not leaving for a week next week I may have already chopped them and started over, but will give them a few more weeks to see if get anything out of it.

At least with the big pots they are VERY low maintenance, if I water before leaving will not need water while gone. But my other 3 ladies under the DS200 and my mothers will need at least one watering while gone, will try and make it as easy as I can on my house sitter.

molasses can be fed every time you water. it helps break down the nutrients in the soil and inside the plant to make them easier to use.

 

[B A R]

& all along I've been thinking molasses was just for the flavor of the smoke.

 

[Crawdaddy]

the way i understand how molasses works is it feeds the microbes that work in the soil to make it easier for plant to absorb nutes.

 

[B A R]

So now that I know there's a purpose other than sweetening the plant, which type of molasses should I buy?

you don't have soil microbes, you use nitrates lol

molasses has a tiny bit of nutrient value on top of being "easy" sugar to digest. its made of beets that's already fermented, so it's really for the microbes and the plant to use. the good stuff smells like soy sauce.

biobizz grow is a nice thick molasses and is cheapish

I think you're good to go with the tiger bloom. it has all it needs in it, but if you like giving it some extra SUGAR! then get some molasses. again, idk if it works with synthetics, but you can try

it's like a nice warm bath for the roots

 

[B A R]

You can't say that. We don't have any idea what's in that NYC COMPOST.

 

[b.real]

that's true. problem is, when you add tiger bloom it kills all the flora/biota/microbes in the soil.

fish wont don't do, sea kelp wont do that, "meals" won't do that. they feed the soil and the plant

here is the biobizz label

Derived from Beet Vinasse (aka molasses)

"Vinasse is a byproduct of the sugar industry.[1] Sugarcane or Sugar beet is processed to produce crystalline sugar, pulp and molasses. The latter are further processed by fermentation to ethanol, ascorbic acid or other products. After the removal of the desired product (alcohol, ascorbic acid, etc.) the remaining material is called vinasse. Vinasse is sold after a partial dehydration and usually has a viscosity comparable to molasses. Commercially offered vinasse comes either from sugar cane and is called cane-vinasse or from sugar beet and is called beet-vinasse.

In the process of distillation of the alcohol and as a result of the heating in the distillation process, in the pulp of the beet reactions of condensation and predominantly molecular ruptures take place. This causes a high fulvic acid concentration in this byproduct. One use of vinasse is in thermophilic digesters. In Brazil thermophilic digester is a source of biogas using pure and hot vinasse as the source of production of methane. In the past, vinasse was a problem in production of ethanol, but vinasse is also a good fertilizer (at least for some time) and a source of methane that can be used to generate heat or electricity.

Don't worry, I won't be messing with that TIGER BLOOM anymore. That was some of the garbage I bought when I 1st went out shopping. You know; So wet behind the ears that the store salesman says "How much you got to spend, I can set you up to grow weed"

I mean you payed for it.. use it up. just really make sure you flush it out before harvest (2-3 weeks prior to harvest in my experience) or else you're gonna be hacking on some ammonium nitrate! I've seen really green bud that even sparkles when you smoke it! that's how you know there's fertilizers in there that haven't been flushed.

problem with molasses is that it's not a strong feed, so it won't last and you have to spend more money on other products.

the only organic (that I know of) that is an all in one is the fish! the FISHY!

you should join my snow white journal. im experimenting with my urine LOL (cleaner than chicken or horse shit/urine, bone meal, feather meal, blood meal that's sourced from who knows where, right?)

Update on 3 ladies under 200 W Diamond Series LED...

They doing well still buds are forming.

I am thinking a MG deficiency is starting to show on my Hawaiian Snow. Will spray down with some epsom salt solution.

Another observation about the Hawaiian Snow. When I grew the mother of this clone from seed, in my TEST grow, it took 2-3 weeks before showing any buds, this plant is obviously showing ALOT sooner. Also it did not seem to stretch as much as from seed. Think maybe because plant more mature? From my stoner knowledge banks I am seeming to remember that Sativas can be more like that, are hard to get to flower if plant not old enough.

Anyhow pics, get close ups this time cause some baby buds forming.

the type of molasses you want to use for plants is unsulfered molasses.

Happy Thanksgiving
