What is the problem with these babies ?
    #630398 - 07/04/12 08:48 AM (4 years, 5 months ago)

Hi guys, i need some help with the experts here to diagnose what seems to be the problem with my plants.

I'm confused with the problem as being Nutrient Burn.. OR Nitrogen deficiency *looks like it in the diagnose guide*


Symptoms are leaves turning yellow and dry-ish... and eventually whole leaves turns yellow and drops off.. younger lower leaves are turning yellow and drops off too..

I've stopped all kind of nutrients and have been flushing them with RO Distilled water *cost me huge amount of $$$* for the past 3 days.

These are the photos to my  grow.. any help will be very grateful!

Soil Growers:
1. Are you growing from seed or clones?
- They are from variety of seeds ranging from BF Vanilla Kush to DP Purple Haze #1 ... and many other free seeds that comes with the purchase.  not from clones.

2. How old are your plants?
- They are 5 weeks from the day it was planted to soil.

3. How tall are your plants?
- There are different types ... the tallest being 35cm , shortest being just under 15cm (from top soil)

4. What size containers are they planted in?
- These are plastic containers available with bottom holes to regulate excess water . measures 25x25x25cm

5. What is your soil mix?
- This is a question im unable to answer. It is the most expensive (and the best available in my country, Indonesia) which uses 100% organic compost materials. Sold by sacks.

6. How often do you water and what type of water do you use?
- Watered using pH 7.0 Reverse Osmosis distilled water purchased by the gallons, once every day (for the small pot) and once every other day (for the bigger pot)

7. What is the pH of your water?
- pH 7.0 Straight distilled.


8. What kind of fertilizer do you use and what is its NPK ratio?
- Please see image below for my NPK and fertilizer content.

9. Do you foliar feed or spray your plants with anything?
- I do spray with the RO water to mist the leaves...

10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
- Currently im still using a single 400w HPS watt , but i do have another one installed and ready to light it up .. but i did not see the requirement to...

11. How close are your lights to the plants?
- its about 30cm away.. not too hot for my hands. and it is air conditioned cooled. Temps are 30-31deg celcious... depens on the weather..

12. What size is your grow space in square feet?
- Plenty of space..  its a 3x4 meters grow (10x13 ft room)


13. What is the temperature and humidity in your grow space?
- Temperature varies from 30-31 deg C (88 deg F) and 60-65% humidity..

14. What is the pH of the soil?
- Soil ph is about 7.2-7.4 .. i know this is a bit too high.. but i've tried Sulphuric acid (battery acid) , lemon, ph Down for aquarium.. but the ph climbs back to normal !

15. Have you noticed any insect activity in your grow space?
- The grow room have been very sterile.. there are no rooms and even gaps for any fuckers to come in.

16. How much experience do you have growing?
- I do have a previous experience (successful) using hyrdrophonics.. but this is my first time using soil . I'm unable to get my hands on good nutes for hydro in my country. Hence, i have to make do with whatever i have here to sustain the growth..

Any help is greatly appreciated!

i've tried means and ways to get the pH lower :frown: but im unable to..  i've tried everything by the guides available online.

Tried:
- Sulphuric Acid (Battery water)
- pH down for aquariums
- Lemon juice
- Distilled Vinegar


it seems that the pH is coming back to its original state... and never a permanent fix....

Actually 6.5.-6.8 is the standard for soil.  Now watering with a pH of 7 isn't going to be an issue, nor is the 7 something pH of your soil. 


What form of sulfuric acid are you using?  And how are you administering it?  A lot of the pH downs you buy are just sulfuric acid, so depending on how you've been applying it I doubt that's the problem. 


My money is on the nutrient.  With stats like that you don't need much at all.  I would stop watering at this point and let them dry out a bit.  You should only be watering when the soil is dry, otherwise you're going to drown out the root system.


Also the proper way to flush is to put 3-5 times the amount of water to soil ratio through your substrate in one sitting, not over a series of days.  Stop feeding them and they will more than likely recover at this point.

fert burns big time. 

you should be able to save them. but ida soaked them bottom up, not flushing water down. all this does is concentrate the nutes in the bottom the pot.  old bath tub or something you can make a flood with, garden hose in the driveway.. 
this way you get run off in both top and bottom. Then you can stop watering for a while. Id soak them, and a day of darkness/or low light and then Id blast them with a 24hr light cycle for a week. just so they can suck it all up, and dry out some too.. good luck.

Soaking doesn't adequately flush the nutrients out of the soil.  Otherwise that would be the standard man.  The action of the water moving through the soil will actively rinse the nutrients out of the soil, soaking will not.

Im trying to say you need a flood in both directions, up and and down the soil.. maybe because I have the area for a washout. I dont piss around when I get a nute burn. them bitches will go in the shower with a monsoon rain for a few hours.. hence the flood/soaked/washed out..

if you put battery acid on your babies, that's probably why they're screaming!
you should be watering with a PH of about 6.0-6.5 for soil.
buy the necessary tools for the job.
general hydroponics sells a ph test kit that comes with drip test solution, PH up, and PH down.
if your using RO filtered water, you'll need a calcium-magnesium supplement.
you should flush your plants immediately with PH 6.0-6.5 water at a rate of three times the container size. (i.e 3 gallon pot flush with 9 gallons of water)
i've said it before that vinegar and lemon juice will work in a pinch, but should not be used on a regular basis.
they are no substitute for proper ph adjusting solutions.

so flush them babies out and see how it goes from there.





well, i'm not saying that im pouring Sulphuric Acid to me plants. Its been diluted .. by the drops..  to lower the pH to 6.0-6.3 .. and administer to the plants..

and yet..  im still reading a pH of 7.2+ for the soil 2-3 days later...

i've taken the necessary precautions by changing the soil into fresh ones (no-nutrients addes as of now)  and flushed twice the size of the pot with RO distilled water.


should i blast them with 24hrs of light ? what will these effect on my grow ?

What kind of light cycle are you on now?  I wouldn't be concerned with the soil pH.

You only want to lower to 12/12 if you're ready to start flowering, and I would wait for them to get a bit healthier before doing that.


Changing the light light cycle doesn't really change the way the plant takes nutrients, but can cause stress.  I would just leave it at 18/6.

Hello guys! Thank you for all the replies.. as recommended by hawksapprentice and orison319 .. i did both flushing with 3x the amount of the container and changing the pH of my water feeding to 6.5~6.7 average for the past week and i DO get results!!

Here are some pics of my those that Recuperate well ... why im saying that they are recuperating is that these are the ones that is growing new leaves without any yellowing discolouration or any sort of yellowing


















Here is one that is NOT doing too good.. i have mixed feelings whether to scrap this one out...






Temperature is at...




I forgot which ones are which in these photos, but they are a mix of DP Purple #1, Vanilla Kush, BigBud and Liberty Haze ..

and finally,

Does the leaves that is yellow and or sick.. is going to turn back to green or are they going to drop off ? because im not seeing any sign that they are going to return to green...

Since this is a stunted growth , does this affect the lifespan for these cannabis in my growing calendar before turning to flowering mode ?

How long does it take for these sick plants to go back to its 'normal' state ?

i've tried to add 1gram of aluminium sulphate to my 3 litres of soil (for experimentation), mix them evenly  and watered it and had an average ph of 6.5-6.6 .. but 2 days later-today-, i do a ph test and it rises back to 7.2 ! what seems to cause this problem ?

anybody have answers ?

Don't worry about you're soil pH.  Just keep watering and feeding with a pH of 6.5 or so.


No the leaves wont repair themselves.  You look to the new growth to see if they are recovering.  Make sure you let them dry out in between watering,
