The Claw!!!

[tinytoon]

My poor ladies have developed the claw look on their leaves and from what I can tell from reading it is most likely from either overwatering or to much N, this sound about right??

[headshake]

if it is from too much N you should be able to tell by the color of the plants, or other factors.

Sometimes this happens if the light cycle is being messed with. Very common when you use buchmaster.

S. Very common when you use buchmaster.

what you doing to your plants over there? i don't want anything near my ladies called BUCHmaster! lol.

I had clawing really really bad once in flower and it turned out it was N def because of a Ph lockout. Plants need a min amount of N in flower (im sure we all know this by now) but some must be present none the less. I locked mine out with shitty soil and paid dearly with wispy airy hairy quasi buds. I hope you have better luck than I did.

They are in second week of veg so hopefully it clears up before switch

Dude Shake, I think I am suffering from Stoned writing...kinda like drunk dialing. I have been doing this a lot lately.

LOL! That sig line alone get a rep point! It's just too true.


Light travels faster than sound. This is why some people appear bright until they speak.

[Ocotillo]

Do you mean "The Claw" or "The Craw"?

Lol I remeber that episode.

I know that if the plants are starving for N they will start to yellow and such but if getting to much N what is the visual sign besides the claw look? I know that I should know this but what can I say? Momentary lapse of headspace and timing :wtf:

[tinytoon]

I found this from Googling "leaves look like a claw". It is from a different forum but seems informative.


Look...I can only put it this way to you. I have had the same symptom in the past. I learned from some very talented people here, that I had been over using the "N" a bit.

Since that time, I've encountered the same symptom. Keeping the advice I had received in mind, I moved the plant out from the grow room and under regular lighting.

There, I could clearly see some vegetation that was deep dark green. Much darker than it appeared under the grow lights. This is also a symptom of too much nitrogen. I handled the plants accordingly, and things cleared up. Your plant "can" get too much "N" "without" burning.

There are times that a flush can be necessary. I don't know nearly enough about your situation to recommend a flush. I normally reserve "flushing" for emergency purposes. But if it's a choice between irreparable damage to the plant, or flushing the pots...I'd flush the pots.

Having too much "N" during flower is a bit worse than through veg. The plants use much more "N" during veg., making it easier for it to just consume the excess.

Prolonged excess of "N" during flower "will" cause flower problems that will effect everything from bud size and density, to flavor of the finished smoke.

Not to confuse the issue any further, but there can always be more than one thing going on. Making a plant show multiple symptoms. In the case of those leaf fingers that look just like Eagle Talons....Nitrogen.

Try getting a good look at the plant under different lighting. There "can" be yellowing leaves on a plant that has too much Nitrogen, so don't let that throw you.

If you can clearly say that they look like a normal green house plant in color depth, then that would be a definite sign pointing "away" from "N". If the plant has some deep/dark green vegetation...look no further.

Hopefully this will help either confirm or begin to eliminate nitrogen.

here ya go.

Thnx Shake :jointsmile:

[GetThisOrDie]

Nice info shake.

I had some clawing once with MG soil and MG nutes. Come to think of it that plant was deep ass green too...

Hope you get it fixed Tiny.

[tinytoon]

they are starting to come around but I did learn something from this ............ do NOT follow GH's receipe for nute mixing. Way to frigging strong for Cannibus, atleast the Medibud strain.

I have just started experiencing the claw,both rooms, everything is normal exceipt the nuit. temp. as no heater yet and the weather has cooled quite a bit in the last week, the broth was down to less than 60 degrees this AM so I need to switch the timer by 12 hrs
so the lights run at night. just a thought,I'll let you know my results.

Temp in my room never goes below 70. Dumped rez this last Sunday and refilled with 3/4 str nutes of what I normally run and they are looking real good now. Will rez change again this Sunday and go back to full strength on nutes of my old mix.

THANKS

I thought I would help out my DWC that we had a few first runs in and plumb them to a control bucket and rez. Well the claw started to come out late in flower but they finish OK. They are dark green too.

Well after thinking about it, I used to top everything daily with ph water by hand. Now with the rez I filled with nutes not thinking about it concentrating when the plants drink up a lot water. By the time for next rez change the PPM's were well over 1200 and getting stronger. Even with latewoods modified it seems the Nitrogen still builds up too much.

Thanks very much for this info. It solves one of my problems.

My other problem was how close the water was to my netpot lids. I did the control rez to be just under the netpots by almost an inch. When you start in dwc you want the water to be close to the netpot and splash it to help get the roots going down. BUT then it needs to drop to about 3 inches below netpot to give a good airgap. Too close will bring on a bad case of root rot from staying too wet. In just a few days of lowering the water level we ahve nice white roots coming out the sides of the netpot once more. So water levels can cause problems as well.

Thanks again.

This happened in my Ebb&Gro setup, my DWC is fine.
Rez temp hovers around 72
