calcium or potassium def ????

[HAPPYTREE]

Im having a hard time with this is this calcium or potassium def or lockout. These plants are 5 weeks into flower and have shown this for about a week.I am runing hydro E/F in hydroton filled pots i flood every 2.5 hrs. I use ro and advanced sensi 2 part supplementing with liquid karma, big bud In the begining of flower and now overdrive this last week.
Ph is 5.8-6.0 constant and ppm hit 1100 but i like to keep around 1000

Is this early clcium or K def???

please any help is greatly Appreciated

DOH the site wont let me upload pics as soon as it will ill post em i just dont want to erase this post

Good move potassium clearly...


I understand exactly why you were confused on the pics in the stitchers guide......


When I first saw her pic thats similar to potassium I felt she had it wrong.....


but there is a subtle difference.....

if you compare your margins with the calcium margins.....

the calcium pics show a dark ring aroung the necrosis where yours do not.....
the dark ring says calcium def....

As for the pic she uses for potassium your pic is better her potassium pic while showing potassium has other issues.....

yours I think is pure potassium def....no other apparent issues....

You may want to verify your ph.... low ph may contribute...

After doing some research on ph.... Im of the opinion that this chart is slightly incorrect... slightly too low.....

This one is better...

I believe that the best range for cannabis is just higher at 6.0 - 6.3

The reason is the misconception that the higher ph doesnt allow for max absorbtion of phosphorus.....

where as others including ed rosenthol and lynette morgan would say the a slightly higher ph is better..... they agree with my findings.... lol I really should say I agree with theirs....

 

[MynameStitch]

Ya I was going to say potassium; now if you had spotting in the leaves with this like it is it would end up being calicum

But I totaly agree with Florigen good advice :tup:

Hey stitch....

Can you copy the pic from the guide that appears just above the zink description to compare...... its the one that looks similar to a potassium def....

 

[MynameStitch]

Yup 1 picture coming right up! Served just how ya like it!

This one I know was calicum; one of the mentors helped him out and he added lime to his soil and fixed the problem; but I can see how they look a like; espeically when yellowing does not start with potassium. Cause it can but not always.

With calicum spots occur within the leaves but starts on the edges just like potassium

Bbiab Gotta get some din din!

 

[Guest]

Thanks.... If you closely look at the two pics..... the margins are quite different.....

In the pic that stitch just posted you can see the brown ring around the necrotic spots.... the sign to me this is calcium....

in the threadstarters pic this is not the case.......

If the threadstarter could take a couple more pics but in focus it would be helpful to compare.....

 

[MynameStitch]

Hey Happy are you using any calicum in your nutrients? how much potassium are you using too cause I think if I remember right to much potassium locks out calicum I will have to read that again though.

What system is your plants in?

hey guys thanks for the replys.

I dosed the plants last week with cal mag(AN) at 3/4 dose.
Sorry for the noob ?s but how do i know exact K amounts in my nutes.
Im running ebb n flow with hydroton only every 2.5 hrs.

Thanks again guys your post have been very informative so far. Ireally would like to get all this knoqwledge dialed in.
Ive studied your sick plant thread stitch ( lord knows ive spent to many hours on this sight) but this lokked so similiar but as florigen pointed out you see the differences>
Ill get those pics 2night

heres some new pics

heres some new pics

heres a new pic of the one i believe we determined was K def and by this pic it looks like some calcium also. the 2nd pic is of the top nug on tis plant.




heres a plant that i have in a dwc bubbler(single bucket) same feeding regime but got ppm up to 1300.
I beleive it looks like calcium def, but i am really interested in having your guys analysis as i just cant seem to pin these things early enough. first pic is a lower fan and the second pic is a nug off this plant




thanks for the help all i hope these new pics can helpout

so what you guys think ???

I think you should make sure your ph is over 6.0


and treat with a product like protekt or meta K(potassium).....

Everyone should have.....

A potassium supplement ....

Epsoms salt ....magnesium....

the two most common easy to fix deficiencies.....


in their fert closet.....

Thankyou florigen and i will be sure to follow your advice. So protekt and meta k are pure k supplement??

Am i correct in sayin that the second plant pic i placed in the recent post is def in calcium. The leaves actually feel brittle and the spots have turned a real tan color(like paper bag color). the strain is kushage and it looks very indica dominant,

Thanks again

You are too close to harvest to do anything drastic.....

Just raising your ph a couple tenths may fix you right up.....

both calcium and potassium are more available on the other side of 6.0


You might treat with some potassium and nothing else.....

if it works you are sure its K.....

if it doesnt.... some calcium is in order.....

neither of those 2 defs are killers at the stage you are at......
