What type of Deficiency is this?

[Merciless58]

Hi Rollitup,

Can someone tell me what is wrong with this picture??

I think its nute burn, but begining to second that.

R/O water
P.H 5.8
Hydroponic: Ebb & Flow
Medium : Hydroton
Pot : 3 Gallon pot
Strain : AK 47, from Clone
about 45 days old.
Lights : Flouro cool white and warm white combo 18/6
Nutes: Flora nova Grow @ 500 ppm

I really cant tell what the problem is, I have 2 other strain from seed growing along and they seem fine.

This is happening on the older fan leaves and the new ones grow fine, then the tips look like they burn and then i get brown spots and then this...

Please , anyone help.

I forgot to mention, this clone was taken from a "mom" who was in Foxfarm Ocean Forest soil. I use hydro.

nutrient burn, your over feeding.

AK is one of those nutrient sensitve strains are you sure you are only running 500ppm? I personally don't like GH nutes when was the last time you changed your rez out completely? If you just keep adding water and checking the PPm you could run into problems. It could be to much nute for your low light conditions.

Hey, thanks for the reply, Yes im sure im running @ 500ppm, I use a tds meter. As for the resevoir change, I have not changed at all . I do the "lucas" method of adding back nutes and topping to keep the ppm at a target ppm. the thing is, I have 2 other different strains and the are doing fine.

I did read once, and i dont remember, but I read that AK can be real sensitive to nutes. could this be the case here?

Sounds like its just good old AK bro if your other plants are doing well. Drop the PPM a bit and see how she responds. You could also try adding more light and see if she starts to take advantage of the nutes.

Yeah, I am thinking of adding another flouro, I really dont want to dilute the nutes, because of the other plants I have, they are taking it up very well and i dont want to deprive em of their vitamins.

Maybe i'll just transplant into a bubble bucket and run her separate from the flood table @ 300 ppm. what do you think?

Now, my next question is, if she is having this difficulty with 500ppm, what would you suggest the target ppm should be once she gets cloned again and be put under a 600 watt hps for flowering.

My first and only crop i fried my plants, (bagseed) but still, i killed them. That was my noob mistake, I used flora nova bloom straight from the begining of 12/12 Big f8ckin mistake. I remember ppm was around like 1400 lol look what it did to it.

Its hard to say how your plants will respond under more optimum lighting conditions. From the grows I have seen of AK they tent to require about half the nutes for veg and about a third less for flower give or take depending on conditions. The best way to know for sure though is trial and error just be light handed with the nutes and watch your plants carefully for any signs of distress.

yes diff strains with the same rez could be a bitch. Ive done it before with 2 seeds and 2 clones and will always separate them cuz u will always need to adjust for the other and one won't reach its potential. run like 300 ppm for a while

 

[iBLaZe4tozErO]

seeds adjust to their enviro better.

WOW!!! getting nut burn at 500 PPM at day 45.. That is something i have never seen. Is this Flora Nuts Organic? Even then you run organics at about 800 PPM. I have grown a few Nut sesitive strains, and never seen one burning with 500 PPM at 45 days. But Hey, I have never grown AK-47.

Have you ever flushed your grow medium of Salts? Could it maybe that they are deficient from under feeding, or maybe a Nut Lock out from high salts? 500 PPM is nothing, even for organic nuts, and a sentitive strain.

Just my opinion. Not like I am Jorge or anything.

I totally hear you, Im thinking the same... like 500ppm?? wtf, that aint strong. Flora nova nutes are organic based. not completely organic.

I will try flushing with r/o water ph at 6.0 and see what happens.

Should I flush and dont feed for a day or what?? Im hydro.

I think when they are ready to flower I will start @ 400 ppm for the flowering cycle. does this sound about right?

I really dont want to kill or stress this plant longer, other than that, she seems to grow fine.

Thanks newgroth

what is the easiest method to flush in hydro? i use hydroton as medium in a 3 gallon pot. any suggestions?


thanks

 

[Lord Dangly Bits]

Flush each plant with 2-3 times the volume of the pot or growing medium with PH'd water. WALLA FLUSHED. So if you are useing 3 gallon grow bags, then flush with 6-9 gallons of water. That is what some people say. Me, I would just use about 4-5 gallons of water. for Hydroton I would think that as little as 3 gallons of just plain PH'd water woulkd work fine.

But I am still wondering why you are going to flush. I highly doubt you have a salt build up, seeing as you are useing such a weak nut mix.

Thanks lord. Well, as far as flushing goes... since I am in hydro, using hydroton, does it matter if its r/o water or tap?? as long as the ph is at 6 right? please let me know.

I am wondering myself should i flush, I have some clearex I bought and never used. The thing is Lord, I have used these hydroton before, my first F*cked up crop, but i did rinse heavily after i chopped em down, I placed all the clay pebbles in a container and rinsed and added dish washing soap, cleaned dried and re-used. could this be the issue?

I will post pics of my setup.

 

[sublimed]

might not be a deficiency. looks like it could be the result of ph fluctuation.

only reason i say this is because a ppm of 500 should not be a reason for damage.
