Identify this deficiency/problem! (w/pics)

[Guest]

Who can tell me wat this deficiency is?
These leaves are from a flowering plant (6th week) ... I'll post a pic of the whole plant 2moro.

I figure its Manganese def. ... Or a very severe combination of things hahaha




















Cheers all!

 

[oldtoker]

hard to say best of luck maybe a good flush is in order but im sure quite a few things are going on ill post some pics of a very very fucked up entire plant that has been grown in 3 year old leftover soils that my cat pissed on then it froze and now it bairly gets to o i dont know 40 F here so the plant is baiscally just chillin lol,

i was just seeing if this dirt could grow something for other (not herb)use but now it doesnt look good.

have a good one

6th week could be a phosphorus deficiency.

 

[tree&leaf]

Who can tell me wat this deficiency is?

Looks like good old Mg def to me!

 

[pseudostelariae]

yeaaaaaa i've seen those nasty leaves before..i believe my problem was pH related.

 

[magicbuds]

You'll need to put more info m8 to get a proper answer

Looks just like a severe progressed potassium deficiency.

Need more information like magic said though

[donatello22]

those leaves look very much like I have on my plant or have already pulled off....

 

[MynameStitch]

Hey donatello, I posted in my thread did you get my response?

Your leaves are far different from his...... with yours it's a little harder to tell which damage caused what to what deficiency due to the ongoing problem that has been going on......

Your strain you have is very touchy to nutes.......
So it's hard to tell which is old damage and which is new..... so with your problem; the problems is mostly too much nutrient related causing necrosis and micronutrient lockout......

 

[Guest]

*** I forgot to mention; This def. was starting before I flowered ... I didn't have time to cure it b4 I flowered due to certain time issues :S ... Its got some freakin nice buds tho hahaha, wonder if they would of been even better or worse if it didn't hav the def. lol ***

Are you sure your calibration is correct on your equiptment? = Yes.
When was your last feeding change? (ie. grow-bloom-micro-additional) = 2-3 days ago.
How often do you clean your system: example: Flush out water replace with clean water and nutrients? = Haven't fully cleaned for bout 3 weeks ... Going to this w/e tho as am flushing b4 harvest in 2 weeks.
What size bulb are you using? = Veg - 400W MH. Flower - 600W HPS (Using this now obviously)
What is the distance to the canopy? = bout a foot.
What is your RH Factor(Relative Humidity)? = 45% RH at day (up to 70% RH at nite)
What is the canopy temperature? = usually bout 22C during lights on.
What is the Day/Night Temp? (Include flucutaion range) = 15C (nite) - 25C (day) occasionally up to 30C!
What is the current Air Flow? (cfm etc.) = Not sure ... Enough for sure tho lol
Is the fan blowing directly at plants? = Air intake comes in under the plants, circulation fans blow around and onto some plants.
Is your water HARD or SOFT? = Soft
What water are you using? = Tap water and water from dehumidifier collection tank.
Has plant been recently pruned, cloned off of or pinched? = No
Have any pest chemicals been used? If so, What and When? = No
Are plant's infected with pest's? = No



***** I've added some ore pics below, maybe some help *****
My apologies if the colors are difficult to see, the HPS lights make quality photography some what difficult lol

 

[EddieShoestring]

the only time that i've produced plants that looked anything like that it was due to a lack of fresh air in the GRoom-have you successfully flowerd plants in that set up before?

e

 

[Guest]

Yea mate, I've grown heaps in soil in there with out any problems, they're not in the pics bt there's soil plants with this one and all of them are fine, no problems wat so eva.
Its really well ventilated in there and has circulation fans and everything, plus that particular fan actually has the air intake coming in underneath it.

Cheers.

 

[RetroGrow]

I could be wrong, but it sure looks like nute burn to me.

 

[Guest]

Yea could b severe nute burn haha!!!

All kinds of problems

[Guest]

You have got several problems listed right here.

 

[Guest]

Well if u'd like to point them out that would b great, I've always been a soil growing, its n my blood lol, so a lil help wif the hydro would go a long way mate.

 

[Guest]

What is the Water temperature? = Unknown

What is the TDS/EC/PPM you are using? = Unknown

What is the Day/Night Temp? (Include flucutaion range) = 15C (nite) - 25C (day) occasionally up to 30C!

No ppm's,... you are really going to need to know this if you do not you can expect more of the same.

What water are you using? = Tap water and water from dehumidifier collection tank

Tap water can be pretty bad minimally it should set for a day or three. One day with bubbling three without.

You need to re read your instructions, get a way to actually test your neut solutions ppm's et al.......chemical testing is easy and inexpensive.

 

[Guest]

BTW this looks as if you have burned the $hit outta the plants if you have the PH under control its most likely the neut solution.

 

[Guest]

Sweet. Good info mate ... Jst so everyone knows, this plants is and always has been a disposable lady ... She's jst some bagseed crap and was all in the name of learning a lil bout hydro b4 I tried any hydro set up that would cost me any money lol.

Thanx for all the input, I think I'll have better luck next time when I get some new equipment ... I'll try find some ppm/EC testers but thats one of those things that are unfortunately unavailable to me or are REALLY expensive ... Mite stick with soil till I've got spare money and jst do some more small experiments like this one.

Cheers!
