How do you get the leaves to stick straight up???

[Mackawber]

It's a sign of strength and vigor when the leaves point up at an angle. It's hard to sustain. I usually see it in mid to late veg when the plant starts taking off at week 3 through 6. By late flower you dont see any more big fan leaves anyway that could stand up--by that time the fans are starting to yellow.

Well you said it. But I am a Badmf grower! And I claim to be, lol.
Plants with properly dialed in nutes, temps, light, co2 and humidty will seek the light and reach upwards. Those that think its strain specific I would challenge as I have seen many many grows and ones "on" are like Vons. I am certain you will get a very nice product but til its "on" its just not.

They will learn this. Given the right amount of time.

Keep growing and learning along with us. And be sure to post your garden pornshots too

Tis young man should take his own advice.

Hello everyone
So ive been growing for about a year now and been pretty successful but i have yet to attain the ability to make my plants' fan leaves stick straight up. You know, when the plants are just buzzing with nutrient perfection and they are angled almost at 45 degrees around the nugs?
Early on in my current sour diesel grow they did this for about 3 days (on day 12) when i switched from PBP veg formula to bloom, but ever since then they have been sticking out straight, which is good, but not the best....
I notice hydro plants usually have this symptom all the time, as well as really good soil growers... so..... whats the secret?

p.s., for you 1000 watter's out there, how far do you keep your light from your plants?

It happens when the water levels are perfectly dialed in if you are growing in soil. If there is even the slightest bit too much water, the leaves will not stand up.

That,along with other points made about dialing in is the most straightforward answer yet IMO.Even with environment and nutes dialed in,there are points when media is first saturated or in need of hydration when the leaves simply will not reach for the light.At most points in between when plants are properly nurtured they all will reach for the light regardless of strain or pheno.

I DO have a few plants perking from tome to time, but I don't think the phototrophism should cause perking if there is an abundance of every building block required for growth. (Why stretch for something when it's handed out to you!?!) Just some thoughts.

Deficient plants of other species than cannabis may shrivel, perk, and perform whatever acrobatic acts because their cells turgidity suddenly changes when the concentration of nutritional ions is out of balance.

I'm really sorry if someone felt offended by me saying that suddenly perking of leaves is normally NOT a good sign, and most likely a deficiency of some kind. (Or a stress symptom caused for some reason).

-I'm really interested in knowing how to get my garden perk and such just by dialing in nutes and medium, so if anyone would enlighten me on the subject I'd be very happy.
(I'm just about to get my license as a plant producer and could really benefit by having plants that perk as they don't need the same space and can be grown closer...)

As I said: Keep on learning...

I believe it is when the roots are getting the optimal level of oxygen. If you give a plant a dose of Hydrogen Peroxide you get the same phenomenon.

....just might be. Or when they get too little water maybe? I'mm not able to monitor that in my schools lab/nursery. But my coco-slab weed may exhibit a little stiffer and steeper leaf angles when the slabs are at their driest.

I've had several grows indoors and never tried anything different or fancy. Is hydrogen peroxide helpful? How much is too much?

As for the fan leaf issue here, my fan leaves tend to be huge bending their stems. Bigger than my hand anyways. Also the bud leaves are all twisted and bent. The budding looks good and I have no complaints.

Have a great day!

She is pretty happy here


And this is what she looks like when thirsty


I just like looking at my girls when they are happy. I love the color of the green in those fan leaves

This is a happy girl. Is this what you want to see in fan leaves?

It's like a plant smile

My leaves are just starting to all shoot up…room's gettin' dialed...

 

[bigganjabud]

Using nft i only see this regular if ive rooted out my cubes properly and they look like upturned old rastas

 

[furrywall11]

or just heat stress....

 

[ChasingGreen]

They usually do it after they have been very dry and lack nutrients and you give them a good feeding. A lack of light will also get them reaching. I love seeing them after they have been fed and they thank you.......

I disagree here, since this wouldn't hold true for a DWC grow for example, where they're never "dry". It's simply the plants saying you have given me the right amount of light, nutrients, and a great enviornment, and they're acting as moving solar panels, thus the "striaght up" look.

When the leaves are like 45 degrees or more pointing up from the stem, I take this a sign that my plants are happy.

Its when the cells are filled its called

When the plant is in this turgor state uptake is going on as fast as it possibly can.
When I see plants reaching like their standing on their tippy toes trying to be all they can be.
Its your plant talking to you .
Telling you that they are happy, happy , happy!
I strive for my plants to take on this reach.

I get this often when I water in some aloe.

 

[trichrider]

im not the best grower nor do i claim to be but im sure the leaves are supposed to be sticking out to the side, not up. In my experience when the leaves are angled up it is because the lights are too close and they are evaporating the moisture in the leaves too fast and the leaves angle themselves against the light to minimize their profile so that less light/heat is striking their surface.

ratzilla and stihgnobevoli are both correct, i think vonforne nailed it too...

text did not follow....K regulates transport of water and nutrients. sun causes osmotic pressure (and turgidity is a function thereof). so if your K is whack, you probably will not see your plants praying.

 

[Ratzilla]

Also may I add that heat stress at least the kind I see is a cupping a canoe if you will of top leaves.
