Downwards leaf curling

this happened to me last year on a few plants *I believe* I put too much blood meal in the mix.


heres something to read from a sticky in this section

""Now for having too much nitrogen in your growing mediums or soil. New growth will be very lively and plant transpiration will be high, but not always.
Nitrogen toxicity can be seen when there are very very dry conditions almost as if there was a drought, which may show a burning effect. Also the big fan leaves will have “the claw” look. The tips will point down but the leaves will stay up as if when you bend your fingers downwards. Leaves can be twisted when growing… mainly new growths.
Yields will be decreased, because to much nitrogen in early stages of flowering slows down bud growth.
Too much potassium and nitrogen will lock out calcium as well.""

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

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'm not gonna get into some dick wagging session with you, I really don't care what you think your experience is.

The fact remains, if you're using a proper nutrient lineup then looking at some leaf chart trying to isolate what you think is missing is pointless.

Look at all the growers who start yellowing 3 weeks into flower and will start hitting it with extra veg nutes or cal mag before even checking their PH or thinking of rootrot etc in hydro.

I've done my time in the trenches, I've troubleshot plenty of medical grows in person. If you wanna continue to argue this lets take it to PM because I don't wanna hijack somebody's thread with this petty faggotry

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.

exactly what i have found, my old stinky pinky x ecsd did this and so does the crosses i made from her, doesent effect the buds at all in my case, all grown in canna coco with canna nutes, ph 5.8 to 6.2

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.

Oh yeah? In most cases except when YOU are handing out the advice I see.

Arrogant fools give others neg rep, then chastise others responses.

Your advice (just re-plant) is in the same category that you criticize others for.

Let it ride. If you do anything just do one thing at a time otherwise you have no idea what works. But I say let it ride. Could be that particular plant is more sensitive to something in your setup.
