Downwards leaf curling

I'm getting this odd leaf curl on one plant. Its in LC#1 soil with blood, bone, and kelp meal in the soil and are watered with r/o water. I have a few other plants in the same soil but none are showing this curling.

kcoc,
In your second picture, it looks like you have nute burn on your leaf tips. How much blood meal did you put in there?

Looks like it got over watered.

I don't think I'm over watering, the whole doesn't seem to to drooping the same way.

kcoc,

1/2 cup per cubic foot.

hmmm, nute lock.

ramhorning caused by lockout,

what nutes you using?

whats the ph going in, whats the ph of runoff?

Whats getting locked out? How do I got about fixing?

heat,water,PH These are the things you need to check into.

Tent never gets over 84 (so far). Water is all from the same source no change on any other plant. I know my waters pH is 6.3, not sure about the soil itself.

I have seen this when I started to get root rot one time. I have also seen it feeding or roots sitting in water. Not saying why yours are just what I did to cause similar look. Basically some of your roots are experiencing something they don't like.

Too much N. (nitrogen) given over a period of time.

You will get burned plants and nute lockout of this continues.

The leaves should also be taking on a dark green appearance.

Gotta tell you a little story here.

My first time growing I had only one kind of seed….plenty of it, but only one genotype. And I had “rams horns” like you have.

I read and read about all the over nitrogen, lockout, overwatering, soils, nute deficiencies etc….but alas, nothing helped.

It turns out (because I’m still growing it) that the geno in question simply needed more light than the others.

Based on the idea that your other genotypes are doing well (and all things being equal) and this one isn’t….I’d suggest an experiment with finding a way to get this particular strain more light.

In my situation that particular strain is presently happiest outdoors (full sunlight). But you may not have the freedom to move the plant outdoors. So my present question is what is your lighting…..and what can you do to increase it?

I’ll subscribe…..it’s possible that the traditional solutions might not be appropriate for this geno.

I think a cup of bloodmeal per cubic foot can be too much, especially if there's not enough dolomite or oyster shells or something to buffer against low ph from ammonia in the soil. Also contributing factors can be too little air circulation, either from too much (frequent) water or too little drainage material like sand and perlite. It does look like overfert, though I associate the clawing with too much P, was there a lot of bone meal too? There is no magic amount of fertilizer to use. It depends on many other things in the soilmix and general environment, as well as with the size, age and health of the plant that goes into it.

Roots aren't liking something. Pop the pots and replace old with fresh soil, water lightly and wait 3 days then give a full watering/feeding.
Move the plant to another location in the room, the light and air circulation change may help, and help identify the issue.

Give em a dose of Lilly Miller brand Plant starter w/ Vitamin B1... It'll clean any dead shit from the roots and encourage em to grow more.

In most cases that doesn't matter, trying to identify whats going missing is the stupid way of doing things unless you create your own nutrients.

Posting the PH of your runoff as well as what you PH your feedings and waterings to will let us know if your soil PH is out of range.

Runoff will tell us a lot.

also if your room is getting as hot as 84 degrees without CO2 you may be stressing the plants, it would be a good idea to pull back to the mid 70s or start using CO2

What a load of bullshit.
In "most cases" it DOES matter...

Identifying the exact deficiency and cause of lockout are imperative to resolving the issue. To say that it's a stupid way of doing it may provoke some colorful replies.
In fact Runoff, or RO Ph will tell nothing about a plant that is locked out or having uptake issues as the soil is out of balance and nutrients aren't being used properly.

Overall temperature is somewhat relevant since the issue is localized on one plant. Which indicates room location, lighting, spot temperature, or poor ventilation/circulation in spots.

Plant got move to a differnet part of the room, I'll re-pot later today in new soil. How much can I break up of roots and dirt with out hurting the plant? Can I use super thrive instead of Lilly Miller Plant starter?

I know I added some dolomite lime.. maybe a cup or so? It was the pelleted type and not the power kind. Could be breaking down too slowly to buffer?

If its only one plant showing symptoms i would suggest it may be a genetic trait. It may be a little more sensitive to the nutes being a little hot.

It doesn't really matter, if you're using proper nutes then trying to isolate what is getting locked out doesn't fucking matter at all.

Busting out some leaf chart and trying to pick out which one yours looks like is the most counter productive thing you can do. Look at how many growers try to fix "deficiencies" by adding more of what is getting locked out. When they should have been fixing some other issue that was causing it. It causes more harm than good straight up....

Did you read what you wrote before you posted it?
I remember reading something about that concept in this book:

In a perfect world your method might apply, but in this particular instance the OP has 1 plant that is showing signs of deficiency, not an entire room.
Learning exactly what the deficiency is for that 1 plant and exactly what is required to resolve and correct it may very likely save the entire crop, if that 1 plant is merely showing the indications ahead of the other plants.

Any experienced grower knows that if everything else in the room is constant and 1 plant deviates, it is usually an early indication that something is likely effecting the other plants as well. They just aren't showing it yet.

Now I won't argue with your assessment further. But I will say that I have diagnosed hundreds of plant problems, many for members here and nobody has ever came back and said my recommendations failed to resolve the problems. Given my track record and the sheer idiocy of your contributions, I will stick with my experience for now.

i personally think its a nitrogen deficiency. im somewhat having a similar problem with my soil grow right now, but its not nearly as serious.

thing is its hard to say if its too much or not enough because my inner growth around the flowers are doing just fine, as to why i upped my nitrogen in the first place, my last grow went great but i had some issue with not enough nitrogen causing my bud leaves to curl like that, all the larger fan leaves were fine though but now im having the opposite problem with nitrogen in soil this time, being as im seeing some fan leaves, very few get a little curl but all my inner bud leaves are growing how i want them to this time around, so im going to stick with the up take in nitrogen anyway.

ive came to the conclusion its possibly this flora nova bloom, ever since ive used it its been a real mix up with nitrogen, so im planning on dropping it next round and just either doing full organics or buying some more stable organic nutrients if my wallet permits me otherwise.

most likely in your case the nitrogen has been locked out somehow. as ive heard a lot of people tell me it happens with soil if it isnt properly prepared with measures that can prevent this. so far my first soil grow is going fine but i noticed how dark green my leaves are which has worried me but again like i said the inner bud growth is growing perfectly so its prevented me from trying to fix the problem too much until i see some more severe signs, in my case i just truly believe its the flora nova bloom as its very high in nitrogen, probably was bad idea for me to use flora nova grow this time around to experiment and see if it actually made a difference as that is even higher in nitrogen and probably the source of some of my fan leaves gettin a little curl.
