Looks like fan burn to me athough pic quality aint great

fan burn? i can do something for that? maybe i can upload all of them in better quality..

What kind of soil and what kind of "organics", and how are you feeding?

i use bio grow mix for soil and organics i use general organics serie and i feed them 1 in the morning and 1 at night and spray them too.. i have 3 and 1/2 weeks and i work them 18/6....

I'm not familiar with any of those "products". Seems to me you might be over feeding them tho...........Looks like nute burn, but thats kinda hard to do in true organics.

so is there anything that i can do now?

Stop feeding them for a few days. What's the recommended feeding schedule for those products?

http://www.generalhydroponics.com/genhydro_US/feeding_charts/GO_MYSF-FeedChart.pdf the schedule programm...There are on the 3 weeks and 1/2... stop feeding them means only water ?

Yep, only water for maybe a week or so. Are there any nutrients "pre-packaged" in that soil you are using? I am strictly an organic grower, and I'm real dubious about the bottled "organic" nutes, especially those marketed specifically to the MJ grower. There are some good liquid organic nutes, but they are marketed by the mainstream nutrient companies.

I just went to their site, and don't see the soil you mentioned.

OK, it DOES have added nutrients. Even tho it says "lightly", there is usually enough nutrients for at least the first two months without adding any more.
I looked at the General Hydroponics website, and I don't know what to tell you about them. I do know that they don't give any NPK values for any of their products that I could see. They sound kinda like the movie Idiocrasy to me.."Use Brawndo. It's got what plants want. It's got electrolytes".
You really need to learn how to use a product based on it's NPK value rather than a "Cake Mix Recipe". In order to be a successful grower of anything, you need to understand plant nutrition, and if you are gonna grow organically you need to have a good basic knowledge of soil structure and soil micro-biology as well. True organic growing is really quite easy, and very forgiving for the beginner, but there IS a learning curve.
It would seem that you have fallen victim to the hyped up marketing of the MJ nutrient companies. Just because it SAYS organic on the label, doesn't mean it is. Everything I use in my garden (when I buy anything) comes from a mainstream nursery or nutrient company, not a "Hydroponics" company.
But back to the issue at hand, that soil looks OK, you just over fed them. When it comes to growing, less is more. You'd rather have them just a bit on the hungry side than over fed.

thx m8... as i said i am a noob grower thats why i ask for help... i will just water them with pure water for a while and we will see......thx for your help again.. and i will post photos after awail again

Please do. And remember, every one here was a "Noob" at one point.
