Leaves pointing up at about 45 degree

[Emilya Green]

if i could draw a diagram i could show you how a plane that is at 45 degrees is reducing surface area.

and even though you can mathematically prove this to be true, mother nature is 5 steps ahead of you. A large amount of light penetrates those leaves and goes on to supply energy to the other leaves below. That angle is exactly the best angle to allow the most penetration of light energy, while also allowing for maximum absorption.

i have a par meter now, my plants were light stressed and/or burned.
the par was over 1100 and i had no co2 supplementation for approx 3 weeks until i started seeing issues with my leaves

so my leaves were praying because of light stress
OP leaves arent even praying IMO
they just look normal, im intrigued at what he would consider not praying ( probably was drooping the whole time)

do you have a picture of the plants as you were baking them? I would bet that your leaves were canoeing too because yes, that was a lot of PAR! Im sure that until they started to bake, they were doing the same thing as our OP, trying hard to use all of that light and let as much of it pass through as possible.

these pictures are out of order, im at work so dont have time to sort them all out but these are some pictures from the beginning of the light burn towards the end.

you can see the leaves praying in one of the pictures at the beginning of the light stress

Most of the time, when plants do this, they are very happy. Most growers refer to this as "praying" and it's completely natural. Good work!

right on learn something every post I read on this site

I would say that this was "before" the light stress. Once the stress started, definite cupping and canoeing is seen.

My plants start praying an hour or two before the lights even turn on.

That right there is the proof of sentience... anticipating the dawn.

I never said my plants were praying at all i just noticed them pointing up to about a 45 towards the end of my light cycle just wondering if that was a normal thing as i havent done this before, like my top 3 pics are how they are for most of the day and the last 3 are when they start pointing up(if you get them in the same order i see them). Good to see your pics, ya totally different thing looks wise, but they looked pretty good still i'll be a happy camper if mine turn out anything like that

 

[Hdinkleman]

I was going to say they look very happy. I recently planted a Fruity Pebbles clone outside and their leaves are doing what yours are doing. The plant is growing like an half inch a day at least


1st Day Outside

Today 9 Days in

i see what you are saying. try checking out a time lapse of any plant growing and you will see how the new growth is vigourously shooting upwards causing that.
i have seen it myself as well, i never thought twice about it.
praying leaves i had didnt look healthy to me lol
my top leafs were roasted and crisp. when they were praying they were already crispy leaves. if i folded them over they would break. they were doing this as they were praying. but whatever they are chopped now and some of the burnt leaves give a nice color after trimmed lol

This my friend is the result of TOO MUCH NITROGEN in you soil or whatever medium you're using.

It's classic heavy handed with the bottle nutrients. We see this all the time.

How I can tell is that your leaves are still green and many are burnt to a crisp and its not from the lights.

420% on this.

I grow plants INTO my lamps routinely and they don't burn leaves like that.

What you have is a chemical burn. Starts at the roots and works its way up the plant.

Suggest nothing but water and see if that doesn't help.

Praying leaves is exactly what @Emilya suggested. Sign of health and proper water uptake and leaf transpiration.

Like this VVV and this bud is VERY close to the light source, I had to tie it away from the light a little bit. If there's enough constant air movement, plants can handle a lot of heat.

i was using 50% of my bloom nutes, its all in my journal.
and whats also in my joirnal is someone telling me a hlg 260 only pulls 205 watts from the wall. when i heard that i used it on 100% at 17-20” from the canopy.
while also using a led bar with uva, Ir and a separate t5 i was supplementing uvb as well. now that i have a par meter i know it was in the range of 1100-1300 ppfd for weeks. it was during those times it was praying
pretty sure it was light burn, but who knows. i did have some ph problems at the same time.
i flushed the plant with 30 gallons of water at week 3, so how it was nute burn is beyond me. new plant is healthiest looking plant i have grown so far. so must be learning something.

 

[Hdinkleman]

i really dont know what the heck it was, i really dont know but oh well. oh yeah and i watering coco like soil lol. so lotta messed up stuff. that plant was abused pretty bad, thats why it makes me chuckle to think it was praying from being healthy lol

 

[GrizzWald]

Those leaves look little toxic. something off, I'd say high ppm without looking into it . Flowers look great . Rot be my main concern .
Exaggerated Praying, sign to me that light needs come down..exaggerated droop (not overwatering) sign to me light needs lifted...

i have seen people say their plants are praying in the morning though, mine were doing it towards the end of the light cycle not the beginning. could be different things we are talking about also, gotta take into consideration the plant as a whole really. i had a bunch of crispy discolored leaves on the top canopy of my plant that went along with the praying, and seeing some older pictures those are the same that are now crispy and break if folded so i dunno, maybe just a coincedence or a confluence of other problems with the plant. im a noob so i have seen many of these problems first hand within the last year

i can post pictures of the progression of the leaves in question if youre really that interested in it

The thing is if you are going to give your plants more light then you're going to have to give them more food as well. It's definitely possible that your leaves were praying to the light because they were enjoying the intensity of it but that doesn't mean that you're plants had the nutrients it
needs

Praying plant = Happy as a pig in shit plant.

If you were already too close to the light and all it took was the leaves to raise up a bit to burn them... that is on you. It is not light stress causing them to lift up. You were too close in the first place.
This is exactly the problem.. some people out there actually profess that this praying indicates light stress.... it does not. The leaves are pointing at the light to get the maximum light possible... not to shade themselves in any way. I don't see how it can be seen that this action is in any way reducing surface area.
As a matter of fact, along with this pointing, you will note that the leaves have puffed up and and all spines and ridges are elevated... the leaves are actually trying to increase their surface area to the maximum... but it has nothing to do with the light being too strong... it is this light that is providing the energy for all of this to happen, and the surface area is being increased so as to increase the leaf's ability to evaporate moisture. It is this throwing off of moisture in the bright light and good breeze that allow the plants to draw up massive amounts of water and be able to develop enough water pressure in the trunk to hold the entire plant upright.

Gawd! Same exact story here. Exactly!!!. So glad I came here, I was going to raise my lights! My little girl (first try ever) is digging it actually! Thanks sooo much guys!
