Shiny Leaves! Good Or Bad Problem IDK! What Caused It??? IDK!

Keep an eye on the leaf tips. You will see them elongate and curl down like in the one picture posted above when you go too far with the N.

Cool, its worth trying anything to get ahead of the competition.
Its good to be able to experiment, its not something a lot of will risk doing with our whole regular crops.

In the comp I was stressed about everything from light to watering and feeding.
This time it is no trouble and has no appreciable affect on my regular indoor grow.
I have a 3x3 veg tent in one room and I'm flowering in a 10 x 10 room using a 6 x 4 area with 2 600w hortilux hps fixtures.
I have two solo cup plants sitting on a table out of the way of my flowering plants.
The second plant shown below #1 was done no-till. After plant #1 was harvested in the previous comp I cut about 2 inches off the bottom of the rooted soil and cut out the center root and planted a seed that was germinated in a paper towel. Top dressed with castings, DTE Bio Live, a pinch of gypsum and dolomite lime.
Somehow I feel like growing well in a solo cup will benefit my grows in larger pots.

The shiny leaves are a shock to me still. Can't remember ever seeing a plant shine because it was thirsty. I also had lower than normal humidity today, 30% vs normally 40+% so who knows, maybe it was other factors that I'm missing also.
Anyway, I think they are continuing to perk up.
Here are both plants now. The second one had a less noticeable shine that also went away.

they look over watered(only leaf drooping, not the stem). they should be drooping(both leaf and stem) when you're about to water them. if you're not watering right, and you're gonna end up with root rot. especially with that small space the roots are in. when you water btw, you should be completely saturating your pot. i dont understand why you're avoiding run off.
could be heat stress(on the bottom), but i have a strong feeling youre just pushing it with the N with how dark your leaves are.

I don't take a stance on either side. Saturating vs not. This is one of those areas where I feel different growers are both successful doing it each way. Many have success without run off. Many have success with run off IMHO.

Hey Kushash.

So solo cup challenge im assuming?
Man im amazed how big you guys get your plants, with such a small root ball. That challenge blows me away all the time.

Maybe try the same ec, for your feed. But add just a touch extra PK?
Maybe a little N toxicity because NPK is a touch too heavy on the N side?
Wouldnt surprize me transitioning into bloom.

Just a thought.
I had the same thing happen to myself last grow, with a different nutrient. PK 13-14 fixed it right up.

Hi Tim! Thanks for stopping by.
Any thoughts on the shine? I saw it this morning. I did not recall seeing it prior to this morning. Humidity was 30% vs the normal 45%.
I water the plant and a few hours later the shine goes away.
Just never noticed that happen in a solo cup or a bigger pot.
IDK maybe I just never caught it before. I figured if it was that thirsty the leaves would just drop but not shine prior to dropping.

Happy to stop by man.

Nitrogen toxicity will cause shine.
But so will Phosphorus.
Since you've had a little claw though. Id be willing to bet its the nitrogen.
Unless you over did your ec a touch?
But if it were me. Id probably rinse it clean, then up the PK a little. Same ec, or just a touch less.
It is a guess though.

OK Thanks!

It's 27 days from breaking soil under 12/12 and has only been fed once on about day 17 or 18 with 1 1/2 tsp of marine cuisine 10-7-7. Last 10 days have been water only. Right now I'm going to ride it out with 150 ppm water for a while and no run off but I can see where a good rinse might be a good idea.

Usually I water it a few hours earlier than I did today. She's growing almost an inch a day right now, I'll see what she says in a few days. The shine just freaked me out. I'm still surprised. No way did I think it was going to go away a few hours after watering. I thought no matter what I did it was going to remain shiny and the shine is already gone. Never stop learning with this fucking plant.

I reckon man. Such an amazing plant grow.
Most fun plant to grow in the world.

I dont generally take the ratio's as gospel but NPK of 1-2-2, for bloom seems very popular.
I am leaning towards more PK being the fix.

But honestly. Hats off to you Kushash. You're a brave man doing the solo challenge.
Its a good little comp that one. Even a bit of healthy banter
Amazes me, the plants you guys over there grow.

Good luck Kush.
Give em hell, over there.

May 26th @MichiganMedGrower is gone forever in my eyes. Worried because he has a perpetual and should not be gone for a month. Good news is he was only gone because he enjoys playing in the politics section and got his wrist slapped with a ruler by the ADM. I thought at 1st he was running from me after my comment above and found the exit from RIU but I guess he's gonna be in the next comp after all.
So if you have time MMG what do you think of the shine that appeared and left a few hours after watering. Have any experience with that?​

Yeah I got punished for bad language according to the management.

Glad to be back though. Read back through and

About the leaves. I think everyone has good advise. I agree totally. Too much nutes. Time to back off some. As the pot dries the ec rises and increases the problem. Watering lowers the general ec of the medium and lowers the stress.

I think you are seeing the mobile nutes become assimilated throughout the plant as the water saturates the leaves.

Glad you are back!

I agree with the others also and will not fertilize again till she shows some changes. I appreciate all of the responses.

I just never recall seeing a MJ plant develop that shine when bone dry and have it go away after watering.
Whenever I had a plant that was thirsty the leaves would fall to the side but I never saw or noticed them develop a shine right before dropping.

What I don't understand about this sentence:
"I think you are seeing the mobile nutes become assimilated throughout the plant as the water saturates the leaves."
What I don't understand is how water saturated the leaves making them shiny right before being watered when they had little to no water in the soil. I only water once in the morning and by the next morning they are as light as can be. I have become very good at learning the weight of a plant in a party cup when it is dry or moist.

If you look at the 2nd pair pictures of the plant in the 1st post. Could you imagine anyone saying water the plant and the shine will go away in a few hours? I would have made a big bet that the answer would have been, No Way.

Here they are just now at lights on. They will be watered after the picture. They are bone dry and have no shine. Maybe the shine will come back if I hold off watering IDK, I'm not going to try it to find out.

I have been moving the lights further away and I think they are responding in a positive way to it.

Only fed them once since they were started with 1 1/2 tsp of ff marine cuisine 10-7-7 on day 17 from seed and will continue water only for a while.

Today is day 28. Here they are before being watered this morning. I'll keep going with the water only and monitor them.

I don’t think the shine has anything to do with thirst or watering. It is a sign of nitrogen toxicity. I am saying when you water the nitrogen becomes soluble again and spreads out around the plant and the leaf changes back to normal color. Nitrogen is a mobile element. The thick shiny leaves have too much. Then the excess is moved to other leaves.

The leaves are a bit too thick and shiny for me. I would simply back off nutes. I like to see a nice even medium green thoughout the plant.

Russet/broad mites do that also. Something to look into, they are a bitch

I have to agree with Roger. If it was bugs the shine would not have gone away after I watered.
Yesterday they were back to normal, looking great with no shine. I'm still baffled.
I know what I saw can't be unusual yet I don't know if others on RIU have seen it the same way I did. I'm sure there are others out there that have.

The shine showed up in the morning when the plant was extremely thirsty, I waited a few extra hours extra before watering this particular morning. I water the plant and the shine slowly fades over a few hours and now is gone. Maybe it would have also faded had I not watered it IDK.

I'm probably alone on what I think it is because I never see it discussed but I feel the plant did it for a positive reason and the only thing I can think of is that it was to protect itself from the light. I'm just speculating. Maybe over time someone will see the thread who has experienced it the way I did. Right now I'm speculating it was to reflect the light away from the leaves. It shows in the pictures that the shine started from the bottom and was working its way to the top. If I knew it was going to go away I would have taken more pictures.

Light Reflection: Many desert and alpine plants have light-colored or silvery pubescence which reflects intense sunlight. This remarkable topic is discussed by Zwinger and Willard in Land Above the Trees (1972). In addition to various types of pubescence, there are other surfaces which provide effective insulation and reflection. These latter adaptations include resinous (glutinous) coatings, powdery or waxy coatings (glaucous), and other surfaces, such as scurfy and farinose. There are many other morphological, anatomical and physiological adaptations to environmental extremes of drought and temperature.


I got the above from here. http://www2.palomar.edu/users/warmstrong/termlf2.htm
Cool link with some nice trichome pictures of other plants.

This is also from that link, learn something new everyday.

Hairiness or Fuzziness (Some Are Redundant):

1. • Arachnoid: Cobwebby--soft, entangled hairs.
   • Barbellate: Hairs with barbs down the sides.
   • Bearded: Long, stiff hairs.
   • Bristly: Stiff hairs.
   • Canescent: Dense grayish-white hairs.
   • Ciliate: Hairs along leaf margin forming a fringe.
   • Floccose: Tufts of soft, woolly hairs.
   • Glandular: Hairs with enlarged gland at tip.
   • Hirsute: Stiff hairs, rough to the touch.
   • Hispid: Stiff (rigid), bristly hairs--may penetrate skin.
   • Hoary: Covered with short fine hairs (white down).
   • Lanate: Woolly or cottony hairs.
   • Pilose: Sparse, soft and straight hairs.
   • Puberlulent: Minutely pubescent (diminutive of pubescent).
   • Scabrous: Rough to the touch due to short, stiff hairs.
   • Sericeous: Appressed, fine and straight hairs (silky).
   • Stellate: Star-shaped hairs (common in Malvaceae).
   • Strigose: Sharp, straight, appressed hairs.
   • Tomentose: Densely matted, soft white wool (tomentum).
   • Villous: Long and soft hairs (shaggy)--not matted.
   • Woolly: Long, soft entangled hairs (similar to tomentose).

She received a watering about an hour ago.
The top dressing of marine cuisine and to much N she received 11 days ago may have played a roll in the temporary shine IDK.
N Tox shine doesn't just show up and go away in hours it stays there right?
Does N tox shine start at the bottom and work its way up as this shine clearly did?
No unusual shine now.
Not perfect but to me she looks like she would have looked had I not seen that happen.
Taken just now. Still growing about 3/4" a day and is at 17".

OK!
I've been growing for 20+ years indoors and never saw this. Maybe it happened in my larger pots maybe it didn't IDK but if it did I just never saw the pattern.
It was happening again this morning. I began to water 1 1/2 hours after lights on and it just started, the shine was coming back. Unfortunately I was pouring water in when I saw it otherwise I would have held off another hour and watched the shine develop and take pictures.
Maybe tomorrow.
I'm still not clear if you guys have witnessed this in action.
Maybe it's because it is in a solo cup that I am able to witness it.
Like I said, I never have in 20 years but maybe it was happening and I just missed it.

I did rush to get a picture right after adding water. Bet the shine is gone in a few hours.
Have any of you seen this in action?

i'm wondering if it might not be some kind of root exudate, something that would normally disperse throughout a larger pot, but gets re-absorbed in the smaller container

Sure is interesting.
Lights on at 4:50 AM. I took a picture at 6:00 AM PST before or at the beginning of the shine. Maybe a mild shine IDK.
Just took a picture at 8:15 AM and the shine is definitely developing.
I'll give it a little longer and take another pic. I have a feeling it is going to get shinier.
Not going to experiment after today. I'm not sure if it is hurting the plant. It seems to have recovered fine before.

Pictures at 6 AM.


8:15 AM

Here is something I just observed.
The plant shown above at 8:15AM spent about 15 minutes out of the grow room. In that time the shine faded. Put it back in the room for a while and the shine started to increase again.
Not going to push it any further. Just gave them some water. I'm sure the shine will soon fade.
Many of the guys in the solo cup comp may not have this experience as they are not growing in soil, most are Growing DWC or COCO and it might not happen the same IDK.
