knowing the PH of your nutrients is a must. If you are not bothering to check or don't care, then your plants prolly wont care to perform as you want them to. Also those tips look burnt. How/what makes you add the amount of nutes you do? are you following the label or a food chart or something?

 

[Guest]

yeah thats true ...i worked the most time very succesfull with easy to grow strains and i didnt used ph etc....

but blue m isnt an easy grower (imo)...

for the next grow (a pure sativa ,omg i will be a lot here in cannabis infarmary )i will use it .....

do you think its a ph problem?

we dont use the their soil ...but this is how we fert them


but i dont give them 4 ml like plagron said ,,,i give them 3 ml every week ...

yesterday,i washed the medium

When using nutrients it is suggested that you start at 1/4 label strength and increase accordingly. Nutrient companies are after your money. You would think that they would want you to achieve a magnificent crop so that you would continue to use their products, instead their recommended dosages almost 100% of the time end up overfertilizing you plants.
What do you mean "I washed the medium" - did you flush??
Fluctuating PH's are the source of a number of problems, the most significant imho would be nutrient lockout. Get yourself some cheap PH testing solution from any grow shop or even a pool/spa supply store.

There is nothing wrong with them plants, the ones you are talking about curling? That is from when the plant has it's leaves against a hard object for a period of time. Your plants are 100% perfectly healthy

Congrats on some fine healthy gals.

 

[Guest]

thx guys !

kab:yes i flushed them because of the tip burns

mynameisstitch...thx but this cant be ...no one of the leaves were against a hard object ...some leaves are curling (only a little bit )and some not ...

hi grownow,

i had something similar happeinning to my plants. Turned out to be too much Nitrogen. Try feeding lower dosages.

Also, if you can, increase your night temps by 3 degrees to 20C. It will help plants' root system a lot.

good luck

 

[MynameStitch]

Hey ganja, I can see where you are saying too much nitrogen; but he is not giving his plants hardly enough nitrogen to cause an excess, he is using all bloom ferts.

The problem is if you notice in the pics, the leaves were pushed up against the wall, hense the leaves pointed in an L shape, this happened to me a lot when the plant was not moved around and was growing too close to the wall.
His plants are perfect condition, if he lowers the dosage he may end up having a hungry plant, the plant is happy, but that is just my opinion

too much feeding imo.
leaves are dark green and tips burning and curling. curling comes before the burning, unless you fed them too much, which would make them burn alot faster.

dont feed them for a while 1-2 weeks and they should get lighter green and then start feeding but at a weaker dose.

 

[KABBAGE]

Those tips are pretty damn burnt, and by the appearances, that tip damage is pretty fresh and long! That is a sure indication something is wrong. Too much nutes imho

right on the money, just a TAD too much feed,
the curleing is nitro toxicity.



my nitro tox.

its not bad tho.
itll also go away in about a week try and cut down on nitro. make your next watering RO +sensical/calmag/etc.

tip burning and curing outward. 2 much nutes.

 

[Guest]

hi
how often should i flush ? i did it last wednesday for the first time...

 

[gratefuldawg]

Could be a magnesium deficiency. I've read when the leaves curl up light that, their preyin for magnesium. Plus the veins look darker then the leaves. I'd go with mynamestitch though.

 

[MynameStitch]

personally if it is a over feeding problem, if you flush you would cause more problems and lfush out any other nutrients, if you do have an excess it's barely and not much and only a good normal water would fix the problem and ease up on the nutrients or how often you give it to them,

 

[Guest]

ok thx

a problem doesnt come alone....here is the other







little brown redish spots on the leaves ...the leave colour turns to yellow....

edit this plant will not haze ? whats up ?the motherplant hazed a lot earlier....
