Need help for the nutrients burn on flowering phase

[tariqtatar]

Hey guys,
I was using advenced nutrients ( micro,grow,bloom) for my amnesia auto fem. strain at outdoor.

Despite i did not add the nutrients at the seeding and germination stage,i have started the use at the flowering and pre-flowering stage.

In order to use easy,i have mixed all three nutrients in one big bottle as concentrate form without water,
also i have i applied concentrate nutrients everyday more than 7 ml then watering less than 0,5 lt to the per pot.( reccomended use is 4ml at the flowering time mixed with a lt of pure water)

Anyway Some of leaves edges have been getting dark yellow color and some of them has defoliate, 2 of plants almost 40-50 cm tall , one of it is still 15-20 cm tall which is i had pull off the burnt leaves earlier and its become shorter than others.

What I have done to rescue plants from now on is ; Protect to the plants from direct sun light,Stop feeding with nutrients , and flushing 2x times with at least 10 lt pure ph water for each pot .
What else do i need to do to get regular harvest time and bounce back my plants?

Hello tariqtatar, and welcome to the forum! I'm currently using AN as well, and they tell you NOT to do what you have done, which is to mix them together. You should add Micro to your water first, mix well, and then add the other two.

I am using far less than what they recommend because my strain does not need that much. I suggest that you simply get rid of what you pre-mixed, and use less of each one when you mix them in your water.

Here is some questions and answers from the AN website:



Does It Matter Which Of The Three Components I Mix First?

Very much indeed. Add pH Perfect Micro to the reservoir first and mix it well. Then add pH Perfect Grow, then add pH Perfect Bloom.

But Can I Mix The Three Components Together In A Concentrate Form And Then Add Them To My Reservoir To Save Time?

No. Don’t mix the nutrients together as a concentrate. Put pH Perfect Micro in the reservoir first, then pH Perfect Grow, then pH Perfect Bloom.

Thnx for response alltatup,

do i still need to use nutrients for these plants after i all cleaned it up? if yes , do you mean adding micro first to the water and add with order the rest of both nutrients to the same bottle?

secondly for the next growth , do you think these nutrients are really necessary ? i mean, are these nutrients converting organic plants to the chemichals,right? 

thirdly according to the photos , how many weeks do you think do i left to the harvest time ?

Tariqatar, Nutrients are necessary throughout most of the grow (except when they are tiny seedlings and when you flush them before you harvest the buds). Your plants are small and it looks like your buds are small, so they may have needed much more nutrient, larger pots, more light, etc.: I am not sure what your plants needed because I don't know anything about how you grew them.

You can find nutrients specifically for growing cannabis which are much less expensive than Advanced Nutrients. There are many, MANY factors involved in growing it well and producing strong buds. I recommend that you begin by reading different topics on the GWE website:

http://www.growweedeasy.com

I suggest that you read about nutrients, light, watering and keeping the correct pH for your plants first.

I would need for you to post photos will close-ups of your buds to see if you are close to harvest: do you have a camera that will allow you to zoom in on your buds?

Great response alltatup.

[oldjarhead100]

tari it sounds like you didnt hear what alltatup said you can not premix your nutrients in a jar/bottle you have to mix them in water first .now I have taken most of a gallon of water and added a mix of nutes for 5 gallons of water for my outside gorilla grows where I have to carry it a long ways then when I got out to where I was going mixed the one gallon of nute mix with 4 more gallons of water. I use ageoldorganics they are pretty reasonably priced and they mix well with each other in water.

[tariqtatar]

here is closer photos alltatup ,i took these photos after flush and remove the burnt leaves

second one is the shorter one ,

and on the third photo some leave edges getting white color?

i couldnt find any symptoms for this in here ; http://www.growweedeasy.com/cannabis-symptoms-pictures , is it normal ?

[alltatup]

Tariq, Look at this page: http://www.growweedeasy.com/why-cannabis-leaves-yellow

Your buds are very small, and while I do see brown pistils on the first one, the other two still have many white pistils and are not mature yet. I am not sure, but I think that the yellow strips indicate a nutrient deficiency.

Here is what I would recommend: That if you wish to grow very good cannabis, you must learn to water and feed correctly so that you can produce very large buds with lots of trichomes on them. We already know that you fed your plants incorrectly, so they did not receive the nutrients they needed in the correct way.

I do not know if you made sure that your water had the correct pH levels, which is very important for nutrient absorption in the roots. If you grew these plants outside, then I can assume that they have had good light.

Please let me know if I can help you in any way; soon you will learn to grow excellent cannabis!! ;-}

[tariqtatar]

Thanks very much alltatup , i hope i ll learn soon,

I dont have any commerical expection thats why quality ,taste , aroma and thc level is the matter for me also mostly prefer highly sativa ratio strains because of day time smoke.

So that i do not need to get large buds at the harvest time if it wont effect or reduce that factors .

Also if it effects the taste of natural aroma and gives you unusual trips which is like shity chemichal drugs ,i dont need the nutrients too .

This is my rookie times just wanted get result quickly but i learnt that it requires patience. I have start to grow few weeks ago , 4 seeds of Auto Fem. Durban Poison with more carefully and sensitive.

Yes , i have growing my plants at my balcony which has many sun light.

I use city water which we dont drink it in here you could see all ratios on the below photo ; with red mark you could see the ph rate.Do you think is it fair enough for the plants?

Lastly , The first photo of plant with brown pistils , do you think is it ready to harvest ?

[alltatup]

Tariq, I love the sativas, too!

1. The nutrients do not affect the bud or the smoke, flavor, but it is important to flush the plants during the final week-10 days before you harvest. There are products that you can get that help to get all the salts flushed out of the plants during this process. I am going to use Advanced Nutrients Flawless Finish when my current grow is ready. See this page: http://www.growweedeasy.com/flushing

2. Your pH is too high for cannabis. This may be one of the main reasons why your plants and buds are so small: they were not able to absorb nutrients well during the whole grow.

If the tap water has lots of salts and minerals in it, you must lower the pH before you water your plants. For soil growers like you, the pH should read between 6.0 and 7.0. See this page: http://www.growweedeasy.com/ph

3. You learned that it requires patience: you are correct!!! It requires art, science and patience! AND you must love your plants, sing to them, sit with them, tell them how beautiful they are.

4. Do you know what the trichomes are? They are what will really tell you if your plant is ready to harvest: they turn from clear to cloudy, milky color when they have the strongest and best potency for smoking. See this page: http://www.growweedeasy.com/make-bud...-see-trichomes
It is not so easy to see the trichomes because you must magnify them x60 to get a close look. There is information on that page about hand-held microscopes so that you can see them.

When I zoom in on the first plant, I can see some trichomes on the leaves, but I cannot really see them. And I still see white pistils on the plant, too. She may need some more time. Can you get a small, inexpensive hand-held microscope?

If anything is not clear, let me know.

never mix the bottles together, all sorts of crazy chemical reactions and precipitation of minerals could occur. I'd say that is the cause of the problems.

Always check the pH of your nutrient mix before watering. even if it is "pH perfect" it's always good practise to check pH for peace of mind. for coco/hydro pH should be between 5.5-6.5. For soil it should be 6-7

Lots of popular nutrients are made up of various mineral salts dissolved in a solution, not all fully synthesized chemical compounds (there may be some, I'm not sure). All the popular nutrient brands are food safe and therefore safe to use on cannabis. A proper flush prior to harvest removes all built up nutrients in the plant anyway.

If you're worried about chemicals you could always look into organic gardening. One line of organic nutrients is the General Organics line made by General Hydroponics, a very popular nutrient company for cannabis cultivation.

[oldjarhead100]

Tari I use oldageorganics they are relatively inexpensive work great and organic Your ph is starting at 7.3 it should be 6 to 6.5 . if you are using city water let it sit out open overnight this gives the chlorine a chance to evaporate their are alot of tutorials that will address all of your problems on GWE I suggest you check them out

[NebulaHaze]

I just wanted to agree with the others that it's very possible you have a nutrient deficiency caused by too-high pH. Your symptoms on the last picture remind me a big of a copper deficiency, which is almost always caused by incorrect pH since almost all water sources have copper in them.
