hey guys

Strain - Unknown

Bucket Size - i think 5 litr
Lights - 3x50 watt CFL
Nutrients - we just have limited kind in our country . i bought the best i can get .
it called "Flortis" 7-7-7 .

my leaves are turning light green as you can see in pictures. and new leaves on top stop growing and tips start burning or something else.
any idea ?

Re: I'll need your help till harvest !

Here's a couple of reference charts that might help. I'm not a soil guy, nor even experienced myself as I'm just finishing up my first grow. However the burnt tips might indicate nutrient burn. Do you know the ph of your water and soil? Don't know that I helped much, but it is a place to start looking. Good luck.




 
Re: I'll need your help till harvest !

Is that soil hot? In other words, does that soil already contain some built in nutes? If so they might be getting overfed. I'm gonna say it is either overfeeding or a ph imbalance. If your only nutes are 7-7-7 then they are getting too much phosphorous during the veg stage here. They also look overwatered, you can tell by the drooping leaves but the stems on the leaves aren't drooping, which means overwatered.
 
Re: I'll need your help till harvest !

Thank you rifleman for your help,

unfortunately i don't know the exat number of my pH lvl
its so hard to find a pH meter here ,
i use tap water . it should be 6-8 pH

its hard to decide which one in picture is my problem :D
thanks again
 
Re: I'll need your help till harvest !

hey stealthboat,
the soil does not contain fertilizer , its written on the bag .
unfortunately i don't know the exact number of my pH lvl
its so hard to find a pH meter here ,
i use tap water . it should be 6-8 pH

what should i do for too much phosphorous ?

the garden stores have another nutrient that it is handmade ! and they call it "netherland crystalone" !!
its purple and powder . the store man said its 20-20-20 !!! :))
they don't have enough information about cannabis

thanks again

That's a pretty big range. On either side of 6 or 8, your plant won't be uptaking any nitrogen. My guess is lockout due to a ph imbalance in your soil. Or a build up in the soil causing lockout. Either way, you're gonna need a pH meter to properly correct the problem. Either flushing with pH 6.5 water, or just correcting the pH of the soil.
 
Re: I'll need your help till harvest !

I suggest getting the ph pen somehow as soon as you can, makes everything easy. I ordered mine online, just a cheap $30 one for now. I'd also say you should get new nutes but as you said, finding them is hard. Idk how to reduce the phosphorous efficiently. Keep an eye on the 2 charts rifleman posted, they are very useful

Thank you guys for your replies , i'll do my best to get a pH meter.
after that , how can i move up or down the pH ?
can something like lemon or soap help to do that ? or its insanity ? :))

Usually you would use a pH Up/Down kit to change the pH of your feed or water. You can use Lime to raise and Sulfur to lower. I wouldnt want to even try soap.

i bought the paper model for pH . the digital one was so expensive :(
now , what number of pH will be good for my sick plants ?

i checked the pH of our tap water n it was about 7 . is that too much ?
problems that shown in picture still caused by pH ?

If you look at the chart that rifleman posted, the "perfect pH" for soil is 6.5. At that level all the necessary nutrients are absorbed. Have you flushed your soil? I would flush and check the pH of the runoff to see what about your soil pH is. That should also help to take care of any build up that might be causing the lockout.
 
Re: I'll need your help till harvest !

7-7-7 and 20-20-20 is the same thing=1-1-1 if the parts are divisible within each other,its the true breakdown

IF your starting water is 7, after adding nutrients it should be within range

the pens are expensive,but the paper is not very reliable,it goes by maker,age,shelf life,ect

thank you ultradan , i'll flush them and keep eye on pH . hope they get better soon

thank you c526 ,
so i must look for another nutrient , which elements in nutrients is more important ?
in here they don't have those popular nutrients for cannabis . if the N-P-K is the most important thing , which numbers is best to look for ?
 
Re: I'll need your help till harvest !

Different stages in growth require different ratios of NPK. Veg normally requires higher amounts of N, while flowering doesn't need as much N, but does need higher Phosphorus and Potassium. Check out the Feeding section here in How to Grow Marijuana
 
Re: I'll need your help till harvest !

O-M-G !!
it is happening to all my plants and i'm freaked out :whoa: :whoa:

i must do something as soon as possible . if i lose them , i'll lose my soul

Re: I'll need your help till harvest !

To me that looks like a Nitrogen deficiency. A guess would be that your pH is off and you aren't absorbing nutrients. Nitrogen gets absorbed at a pH range of 6.0-8.0, so if you are below 6 in pH, then you aren't uptaking any Nitrogen. Look at this pic: Nitrogen helps the plants to absorb Magnesium which then helps absorb Phosporus. If you can't uptake Nitrogen, then the plant suffers from lack of other nutes as well, this is called "LOCKOUT". Flush the soil and get the right tools to regulate and monitor pH, and go from there.

now i know that the pH is in range of 6-8
i was just reading the label of my fertilizer , and i find out it doesn't have much zinc and ...
i was surfing the forum and the nearest thing to my problem was zinc def
here are the notes on the label :

N - 7%
P2O5 - 7%
K2O - 7%
B - 0.05%
Cu - 0.01%
Fe - 0.05%
MN - 0.01%
Zn - 0.01%

Hmm... doesn't really look like Zinc to me, but I am pretty new to growing as well, so a lot of what I know is just from hours and hours of research. If it is Zinc, don't overdo the correction, as an excess of Zinc will cause rapid death. This was taken from the Plant Abuse Chart

Zinc (Zn)
Zinc plays a roll in the same enzyme functions as manganese and magnesium. More than eighty enzymes contain tightly bound zinc essential for their function. Zinc participates in chlorophyll formation and helps prevent chlorophyll destruction. Carbonic anhydrate has been found to be specifically activated by zinc.

Zinc Deficiencies:
Deficiencies appear as chlorosis in the inter-veinal areas of new leaves producing a banding appearance as seen in figure 18. This may be accompany reduction of leaf size and a shortening between internodes. Leaf margins are often distorted or wrinkled. Branch terminals of fruit will die back in severe cases.

Also gets locked out due to high pH. Zn, Fe, and Mn deficiencies often occur together, and are usually from a high pH. Don't overdo the micro-nutrients, lower the pH if that's the problem so the nutrients become available. Foliar feed if the plant looks real bad. Use chelated zinc. Zinc deficiency produces "little leaf" in many species, especially woody ones; the younger leaves are distinctly smaller than normal. Zinc defeciency may also produce "rosetting"; the stem fails to elongate behind the growing tip, so that the terminal leaves become tightly bunched.
