Calicum problem?...Pics...

water

water

Are you using 100% RO water ?
If this is the case try mixing it with 30% tapwater no calcium adjuction needed.
And do follox blackmelo's advice.

PEACE

I have backed off the CalMag+ 2mL instead of 5 and have seen no new deff. Time will tell. To Be honest on my last grow I used tap water and had no problems in veg like this.

BTW Blackmelo I have my night temps up and rez temps at 75 and yellowing is already going away Thanks.

With 10 ml pbp grow and 5 ml cal mag plus per gallon of water, you will probably get potassium trouble. This may be what your seeing.

This is wat I think too. Only it will not be a potassium problem but a calcium problem, probably because of overdosage of magnesium.

But what is the EC of the drain of your rockwool? This is important to know if you grow on hydro. If it is too high (>3) you can lower it by flushing with plain water (adjust pH between 5,2 and 6,2).

Peace

What you really need is some STUMP REMOVER! Hahahahjahaha! Sorry sunburst...inside joke! Hey Sprout Dude...how many personas do you actually have? Get off the calculator and grow some cannabis huh?

Listen to Head, he knows his shit.

 

[Guest]

LOL
Hey Monk if everything goes like I want I may need some Stump Remover after harvest to clear out my Flood table.

 

[Brother_Monk]

:friends: Here's to the Big Honkin' Stumps on your flood table :friends:

 

[nocturnalG]

yeah iots important to get the calcium/mag/lk ration correct.

 

[Guest]

PH 5.8 CALMAG+ 2mL seems to be working. Thanks

 

[Grat3fulh3ad]

Good deal... Glad you got that sorted... Just don't ever let the plants find out they have to have a specific K/Ca/Mg ratio, and you should be fine from here on out...

 

[Guest]

^^^ Thanks^^^

 

[Pimp Aurora]

math don't grow plants, sprout....

and bitching at people does?


TROLL WITH A BIG REPUTATION

 

[Grat3fulh3ad]

Troll... lmao...

Keeping the facts straight ain't trolling. Correcting bad advice handed out by botany students who don't grow ain't trolling. Anyone who goes around, calling every lockout or toxicity a K/Ca/Mg problem, and telling people to use stump remover or battery acid on their garden, and has never even grown a plant to harvest... needs to be corrected. Everytime. Not trolling... Smartass damage control...

 

[Grat3fulh3ad]

BTW... please show me 'Bitching' Cause the post you quoted ain't it...

 

[Pimp Aurora]

Just curious BV... you grow?

And suprise surprise your troll friend core throws in his tuppence worth straight after you, come on guys get real eh, look at cores sig ffs.

if that isn't bad look at haze tokers!

fuck me give some responsibility to the end user, let the person with the problem make up their own god damn mind whos advice they want to take and leave it at that like I am just now, have a nice day

 

[Grat3fulh3ad]

Me adding my 2pence does not take any decision making power away from the end user.
'Do you grow' was a valid question, to someone handing out Grow advice, Eh? Especially since I already knew the answer. It's really easy to tell by one's advice, whether they have spent time learning how to read cannabis plants... or only just learned how to use a nutrient calculator, and read an article on ratios...
I have nothing to do with who post what on which thread, and can't answer for core or hazetoker.

 

[Grat3fulh3ad]

In Internet terminology, a troll is someone who intentionally posts derogatory or otherwise inflammatory messages about sensitive topics in an established online community such as an online discussion forum to bait users into responding...

And I did this where?
Just because someone is sensitive to my question to them, does not make it a sensitive topic.
Just because a sensitive person becomes inflamed, does not mean that fault lies with the question.
Was anything I posted untrue?

 

[Core]

lol...not even gonne dignify that with an answer....

Greetings SunBursT

Allow me to commend you on your decisive use of diplomacy in your approach to the members and their advice posted in your thread. Your thoughtful and measured responses, your use of humour as a diffusive tool, your candour, and your transparent reasoning are excellent examples on how to effectively manage a thread. This should be the standard aspired to by the members of this community. Thank you for the brilliant display.

I concur with both pieces of advice offered, and from the contents of the thread, it seems that the implementation of both has proven beneficial. One other point to bear in mind is: in a situation where Calcium is competing with Potassium, a relative humidity of 35 percent is too low. This is the underlying reason for the manifestation of the necrosis and chlorosis observed.

Sincerely,
Charles.

p.s. 4:2:1/K:Ca:Mg...was not "picked out of a hat"; it's empirical. Now that's not to say that a plant won't perform utilizing different ratios, but like all metabolic processes there is an optimum range and a pinnacle point (based and dependant on variable, of course). What is oft times not factored is the role that experience plays in one's ability to circumvent foundational rules. For the initiate cultivator it is often helpful to have a 'blueprint' to follow.

p.p.s. If advice is sound...it should be followed (irrespective of who offered it). Now that's not to say that all advice henceforth (from any particular member) should be implemented, but the role of the community is to dispel the bad while acknowledging the good. If advice is sound...it should be followed.

p.p.p.s. My apology to you SunBursT for raising this issue/concern in your thread; I simply mean it to be a point for consideration.

Thank You CX
To be honest my first grow had a problem and I asked advice. I was told not to follow that advice as that person did not grow. My question was if the advice is sound whats the difference.


Here we are a grow later and I know the diffrence. Every leaf on my plant is the most important leaf in the universe lol I am obsesed with this plant, its care its perfect growth, bringing it to its absolute finest display of flowering. If you have not or do not grow this may seem crazy but the growers know. They worry about my plant, its not just advice its a rescue a mission if you will. thats why i look at their grows etc to make my decesions.

Sound advice is sound advice, but not knowing about who gave it leaves me in the dark as to its soundness. I would have to know the answer to my problem before I asked it to know if it was sound advice coming from someone with no grows for me to study.

Again thanks to all who have responded its what makes this a great place.

Thanks again Sun

From the article on plant nutrition in my sig line...

For many years, there have been a few people who claim that there is an ideal ratio of the three principal soil cation nutrients (K, Ca, and Mg). This concept probably originated from New Jersey work by Bear in 1945. It is generally accepted that there are some preferred general relationships and balances between soil nutrients. There is also a significant amount of work indicating that excesses and shortages of some nutrients will affect the uptake of other nutrients . However, no reliable research has indicated that there is any particular perfect ratio of nutrients.

For an example, in Wisconsin researchers found that yields of corn and alfalfa were not significantly affected by Ca:Mg ratios ranging from 2.28:1 to 8.44:1. In all cases, when neither nutrient was deficient, the crops internal Ca:Mg ratio was maintained within a relatively narrow range consistent with the needs of the plant. These findings are supported by most other authorities. A soil with the previously listed ratios would most likely be fertile. However, this does not mean that a fertile soil requires these specific values (or any other). Adequate crop nutrition is dependent on many factors other than a specific ratio of nutrients. It will rarely be profitable to spend significant amounts of fertilizer dollars to achieve a specific soil nutrient ratio.

While there is no perfect ratio, balance within the range of acceptable ratios is important. Otherwise antagonisms (interference of one element with another) will occur.
