Help?

Hello guys, i'm not sure if it is the right place to post this, but it will do, because i need some help.


So, i'm with some trouble on my grow room, this is the first survivor on a second growing.


my little baby has little dots on end of leaf.
i tough this was Potassium, so i gave her a little bit of NPK. she grew up a little bit, but the dots keeps appearing.


so i tough it was calcium, i gave her a bit, and nothing changes.


anyone has a clue?


p.s: rocks on top are perlite

hey i think you will find our "Marijuana plant problems" area to be more dedicated to your question, have a read in there while waiting for some responses, it can be quite slow this time of the day https://www.rollitup.org/marijuana-plant-problems/

As this is on the closest leaf to the bottom...
It might just be where the soil/perilite mix has had the leaf resting on it...
If top remains healthy, do not worry...
A lot of the time, my bottom clone leaf gets weird...

What are you feeding?
What is your substrate?
Grow method?
Nutrients?
Additives?
pH?
Temp?
Lighting?
Strain?
Source? (clone/seed)
Age?

Anything else that could possible be pertinent. I'm a newbie but I'm trying to get you to post the info so the grow gods that hang around here can help you. I probably can't because that doesn't look like something I've seen. This thread would have been best in Plant Problems so maybe a mod will move you? In the meantime start reading here:

sunni, thanks for your answer, can you move this thread to there please?

Sand4x105, thanks for your attention, it seems to get worst.
Are you sure that if the leaf resting on the perlite can cause this?
Dude, this is not a clone. is germinated! this will be the mother of clones.
i'm worry about that, if this little mother fucker die, everything is gone

May it be light or temperature stress? thermometer displays 34.5Cº, there is a sensor at her foot.

Thanks for all

34.5'c in the shade?
Should be (optimal) 26 to 28'c at 32 the plant starts dying.
Amazed the plant still looks so good.

Anotherlover, is under the light.

get the probe into a shady area below the plant. Check again but seems like it may be heat stress (looking at the serrated edges on the leaves, they seem a tiny bit more pronounced than they should be).

Its stressed. More info needed ,lighting? temps? medium? watering? any recent changes?

Sorry didnt see this, yes its too fucking hot maurice ,the heat must nearly knock you over when you walk in. Get the temps below 26 or you will never produce much, you wont even make the power bill.

thanks for your reply.

What are you feeding? - What you mean?
What is your substrate? - Sunshine mix 6 (couldn't find nº4 here in brazil ¬¬)
Grow method? - rock wool
Nutrients? - NPK
Additives? - none
pH? - don't know yet. (hard to find ph measure tool)
Temp? - arround 34Cº
Lighting? - 600w fluorescent
Strain? - What you mean?
Source? (clone/seed) - seed
Age? - about 2~3 weeks

i did a search for nutrients lack, or abuse. didn't find any matches to this.
also go through the deficiency table.

thanks

HAHAHAHA, so i'm burning this before i supposed to do?

Damn fucking lamps. so what can i do? shutdown some lamps? i have 6 lamps with 120w each.
maybe can i give some directly wind to her. i can program my growroom to do it whenever i want. like: 30s of wind each 30minutes. it can variate however you desire.

what i really need to do now is kick down the temperature, right?

i will post some photos of my growroom controller.

thanks 4 all!

Need to extract all the air at least 5 times a minute from the entire room.
Fans blowing over the plant will help as well.

Buds said the same.
Knowing this, im amazed too now! hahaha, almost burn everything.

the worst thing, is that i'm working at now, and i can't do anything to solves this problem.
the plant will burn until i get home.

I'm working on a solution for this.
my growroom was made from recycled parts
i'm replacing some parts now for better results.

this is a video.
[video=youtube;LNRqHBpwRVE]http://www.youtube.com/watch?v=LNRqHBpwRVE[/video]

i'v made some fixes.
Temperature show at display now.
i will do more changes to it when new parts came.
What this do now?
Control: Wind, Lamps, Water and CO2 tubes.

everything can be programmed.

there is a push-key to change from Seedling to Growing to Flowering state.
on display, you can see a tree indicating what the hell it was doing with the light.
if it has a smile face, so it's seedling, 24hours of light.
if there is a filled box, so it's growing, assuming 18x6 hours of light.
if the box isn't filled, or reaching 4weeks growing, the program auto change to flowering state, assuming 12x12 hours of light.
You can control all the light state by pushing those blue keys, or simply let it do by it-self

The water can be controlled in 2 rules
When and how much?
EX: 50 to 50 minutes, give 20 seconds of water.

in new program, you can control humidity, if it is too low, a car fuel-injector will spray water until it gets on programmed state.

many other programmable settings can be done from main menu (newer version)

there will came new versions, boxed versions. with a friendly interface.

86 deg is max on most mj. I would'nt push it much past that even using 1500ppm co2. This is stunting your plant, very! Get your temps down, by venting your area and light fixture. This hot stale air is not helping your plant. Dry your soil, and watch the "New Growth". Old growth problems tell you, "what has already occured." Now, concentrate on what is happening on the top of the plant. A mj plant will eventually shed these damaged leafs when it is through with them, so leave them alone, they will give to the plant, whatever sugars and starches they still have available in them. These in return will will help your plant right itself. The necrostic parts of those leafs will yellow and die. Snip this death away, always leaving the green portions of your leafs. Don't ever remove them unless pruning for yeild later down the road! See if this helps, no chemical amendments are required here just time also when your plant is in stress I.E. heat, overdose recovery ,infestation etc. Stop feedings.
This little seedling doesn't require Any nutes. It looks like it's sitting in some sort of potting soil now. These soils contain (usually) all a plant this size needs for some time to go.
P.S. I reallize this is your sole survivor. That doesn't mean even if germing fem seeds, that it is a fem. Nothing is certain until it shows sex, thefore you won't know if it will even be a fem, let alone a clone mother.

God I'd have to run a wind tunnel to extract all my air 5 times a minute, My room is 10 ft tall by 30 by 15 foot wide for veg, and 30 by 30 foot in bloom rooms.5 times a minute? I don't know where that bit of miss info came from? What if you are employing c02? If your lamps are properly vented this hot air dosn't even enter the grow area! why does my fresh air coming in at 875 cfm need to be exchanged 5 times a minute? Wow!!! Is there equipment out there that can do this even in a smaller set of rooms like mine? Do guys running grows in 100x50 foot rooms need to this? And if so, how much did it cost to have McDonald Douglas design the blowers for this application?

Lack of air turnover must be what is killing all these!
People should "NOT" assume everything they read on this forum is correct some people will type whatever enters their minds at the moment. Those people should spend more time "extracting" from the forum and less time contibuting with bad info.

melungeonman, nice pictures, wish i could put my electronic creations on a room like that.
your babies look so nice man! can you mail me a bud? hahaha just kidding.

i'v reading all your answers, and one of my problem is the air.
second is the temperature. for mine is to high.
On my video, i'v shown input and output of air. for me that's a problem.

CO2 tubes are to use in a big grow-room, i don't use in my little room.
My controller supports and can handle with this. you just need to say how much and when to open CO2 vales (for me is disabled)

mr. Cervantes said those things about air on Ultimate Grow.....
tonight i will fix air inputs and outputs.
what about light? what can i do to fix?

From George Cervantes actually...

btw, your girls look sexy

"some people" should also listen to the masters (not me by a long shot but the man) or may end up with issues down the line (anyway, enough of this silly practice I have found on so many forums over the years).

My veg server replaces air around 8 times a second.
My flower area replaces the air about once every 2 to 3 minutes (southern hemisphere, if this did not happen they would all die from severe heat stress in summer, average temperature outdoors = 34'c to 36'c).

Anyway, pretty sure if you live in a cooler more built up (more C02 in the air) area this would not be necessary but for us okes that have real summers, some pretty warm winters and more oxygen in the air than we need that is just not an option.

Guys, i'v made some modifications.
Got 29.4Cº, also modificate intake and exaust system.

About 180CFM in.
my grow-room has 150mm X 60mm X 200mm
