what iam doing wrong?

 

OVER fertilized, looks a lot like nutrient burn. Flush your plant immediately, and keep flushing

 

any other suggestions?

i dont really take the words of an 17 years old boy very serious alone...

 

You may have some sort of burn. Could be overfertilization, it could be that your girls are too close to the light source. Take a look here for more help. http://www.icmag.com/ic/showthread.php?t=11688

 

okay thx i will look in to it

^ Thanks for the vote my man! You are still the man. All the advice prior is probably close to what is going on.

It looks like a couple of problems. The onset of nute burn and possibly heat/light burn. Normally, light burn will be on the top looking all crispy whereas heat can be lower on the larger fan leaves (are side lighting? - bulb hanging vertically). It even looks like it may be overwatered as well - only water when needed. I would stop the foilar spray for now - light burns from foilar sprays/misting look almost like a spidermite infestation - little burned spots all over the leaves.

Unless you are using a ec/tds meter do not load up on the nutes too much especially in soil. It is temping to dose them but unless you are very familiar with the strain it is guesswork. Whitewidow, for example, is sensitive to overfertilization and can be killed fairly easily.

You would be suprised how big and healthy the girls get with just mild fertilization, good lighting and proper ventilation.

Just a guess but I would: check the temp of your room keep it in the 75'F range (max) Humidity 50-60%, Let the soil dry at least a fingers depth - feel the weight of the pot to know when to water (when dry you should lift the pot and feel like superman as it will be light - give a good watering and then feel the weight again). Keep the light at a reasonable distance (use the "back of the hand" under the light to feel how hot it is). You will probably want to reduce the strength of the nutes and see how the girl responds. If things look good gradually increase but not too much

Info: Lights? Temps? Distance from Lights?

 

thx guys for all the help

budbill - light burns from foilar sprays/misting look almost like a spidermite infestation - little burned spots all over the leaves.

can this problem also cause small holes to aper on the leaves? "brun-like holes"

lights: 1x hps 400 watt...
distance: 20-30 cm from the plant top/side...
temp: 75-80 "hard to push down" sometimes up to 82... max 2 hours a day...
humidity: 50-55 alltime...
sweet-ass cool-wind blowér fan...

 

It can - the drops act like a magnifying glass.

 

okay thx every one

well it turned out that is was a little over fertilized... I hade some problems fluching the soil so i just change it yestuday and iwe stoped spraying
