need more information

what soil mixture is that and is anything added to it?
you use any nutrients yet? if so how much and how often and what kind and the npk?
what lighting are you using? temps and humidity

one thing i do see is your plants might need food... 2nd your soil is barkey

the yellowing of the cotyldons means its used up all its food and they die,. no plant keeps its cotyldons
kinda like the umbilical cord on a baby, it falls off a few weeks after birth

Stitch, I am using a soilless mix and i think the spaghnum peat when it drys out looks a little barky. i am watering tomorrow with just blackstrap molasses in my water at 1 tbs/gallon.

my soilless mix is as follows:

5x spaghnum peat
3x perlite
1x EWC

2tbs/gallon of dolomite lime.

im currently using about 150w of compat fluorescents 2-3 inches from the plants. i dont have a humidity and temperature reading, but its not hot at all, its in the storage room so i would GUESS between 70-80. it also has a fan blowing across the plant and the lights.

i dont want to use any liquid or chemical nutrients, im trying to stay as organic as possible. my next transplant i might be putting blood and bone meal for N and P. the molasses is supposed to be high in K...

To keep something simple simple; your plant is doing okay. The brown spots could be a slight overfert or a deficiency problem, but don't panic. As your plant grows and get bigger, it will become more resistant and deal with the problem itself. Don't go flushing or repotting, that will hurt it more than this. If the problem stays and grow worse, you will have to deal with it.
Your plant is short and compact. At first thought, that means your plant has all the light it needs. At second thought, young healthy plants grow extremely fast and tend to elongate, and when they're very stout with no space between the nodes, it's often a sign that something's restraining them. I've seen that in seedlings and clones that got overwatered early, or with not enough rootspace, or not enough of something else. It's just speculation for now though. If that fan blowing on the plant makes it sway, turn it away. Cannabis plants needs air circulation, not wind. Young plants are especially sensible to draft, it dries them out and stalls growth.

Hello Rosy cheeks*SMiles*

I have always belived a fan randomly blowing on the plants(Not a constant blow but the osolating feature)
Is Infact good for young seedlings/young plants
It helps to stregthen the stems


This is just what i read before and somit then i have always done(with never a prob)
But i am always open to new idea's,so interested to know more about this

I was also a fan of fans once upon a time, and set one on my plants as soon as they had rooted. The wind mimicks a natural outdoor environment and helps strenghten the stem, that was my motto. Slowly though, I've come to alter my point of view. Air circulation is essential since it replenishes the CO2 that the plants absorb. A light gust of wind every now and then won't do no harm either, but when the wind is persistant, monotonous (as with a fan set on the plants during the light hours) and strong it becomes a stress factor to the plant. All scientific studies of trees and plants grown in windy conditions show the same thing; that the plants grow smaller, more compact, and yield less. The constant wind drives the moisture from the leaves and forces the plant to increase transpiration, which if overkill leads to stress. In my own experiments (results posted at Overgrow), I found that seedlings exposed to strong wind have a higher chance of becoming male, which is the proof the theory wind=stress, since stress increases the male ratio in the sexing of the Cannabis plant. My advice to you is to use some kind of air circulation around your plants, but do not set a fan straight at them, especially young plants. Extraction, intraction or a fan set on lowest speed blowing away from the plants create enough air turbulence for CO2 replenishment. As to strenghtening the stems, shaking the plant or bending the branches gently every now and then will strenghten them. I give my plants occasional showers. It washes spider mites of the leaves and strenghten the plant as well.

Hello again
Yep i remeber you from OG(u had same bag over your head)*smileS*I dont remeber the post you refer to tho


I never have a fan(or advise)blow constantly on plants,but to use the osolating feature...

I see what your saying tho,And even that is not random whisps of breeze(it is a constant(in a way)Cycle of breeze every say 15 secs(as the cycle moves from one side to other)
So every 15 secs Any given plant would be in direct fire of the breeze

So yes i can see just haveing it blowing in the cab(not aimed at plants)Would be better going by what your saying(which after reading i do agree with)


More by chance than design my fans have to be stationary,And for that reason they are aimed away from the plants(No way to use the osolating feature(room is to small and fan's hang from the walls)))

But i have to admit to advising folk in the past to osolate over them,Will have to revise my advice now i think*smiles*


Cheers Rosy
Take care

sprout is right, your plant is sstartihg to show nitrogen problems, but its very small right now

feed some blood meal in the soil its slow relasing, but you will still have to get an fert

and feed weekly
your mixture is soiless so your ph will have to be 5.5 to 6.3

get a ph meter and check the run off
with soiless mixtures you will have to feed a bit more than reaguler soil mixtures
its kinda like growing hydrosoil

right now they could use a organic fert like fish emulsion you could use 1/4 teaspoon per gallon

but whatever tou feed you should always start out the feed 1/4 teaspoon per gallon of water

then 1/2 teaspoon for chemical ferts, but since you dont want to use chemical ferts i thought you should know just in case you couldnt find organics

do you have access to hydro shop?

well right now get some fish emulsion or get a fert ike pure blend grow
that stuff rocks its all organic and kicks ass

use 1 tsp weekly for that stuff

get some soil mixture, miracle grow makes organic soil mixture its got bone blood meal in it
get some of that from hardware store, forget what people say about how bad miracle grow is, i used it through the entire time i grew, if people cant grow with it. its because they are to new or growers mistake, i used it and my first grow i grew out my plant that was 7 feet tall witha 400 watt hps and got 6 oz, if i had better wattage and more space i coulda got much more

if you add that you wont need to feed for a few weeks

wait around 15 to 25 days before feeding therm if you choose that soil mixture

the only product you want to stay away from made by mg and other companies is there moisture control

the mixture holds to much water for cannabis and they dont like it
