IT WAS VERY KIND OF U 2 ANSWER US... THE THING IS, I'M NOT FROM THE U.S.A, HERE WE DON'T EVEN KNOW THE STRAIN OF THE PLANTS. WE DON'T EVEN HAVE ANY SPECIFIC FERTILIZERS FOR MARIJUANA... I KNOW THE INFORMATION ARE NOT SO HELPFUL, THATS WHY I BADLLY NEED HELP. I DID WENT TO A FLOWER SHOP(WHERE I BOUGHT MY SOIL) THEY GAVE ME LIKE A WHITE(CRYSTAL LOOKING) SALT FOR VEGETATIVE, WE USED IT ON A WEEKLY BASICS. FOR FLOWERING THEY GAVE ME A PHOSPHATE(MIX WITH DIFFERENT TYPE OF VERY SMALL ROCKS LOOKING LIKE) ALSO USED ON WEEKLY BASICS AND A FERTILIZER FOR BLOOMING NAME BARONA 1, ONE TBL SPOON MIX IN 5LT OF WATER ALSO ON WEEKLY BASICS.....

IT'S NOT LIKE IN THE U.S.A, ITS VERY DIFFICULT HERE, BUT STILL WE'RE TRYING..... TO START GROWING I HAD TO IMPORT MY H.PS LIGHT FROM THE U.S.A......

PLZ HELP, DO LET ME KNOW IF U NEED MORE INFORMATION OR MORE DETAILS PICTURES OF THE PLANTS(OUR BABIES LOL)

looks like pH is to low. I would flush the plant with water or if possible transplant it into a larger container with fresh good new soil flush with water 3 X the amount or more allow to drain fully move the light up at least a foot from the plant until she starts to stand normally. go organic compost blood and bone fish seaweed. If you have to import some soil order coco its lite weight and big block will expand and it can be reused its great investment potential for you.

thx for the advise 303stoner, i'll try to flush them..... i had another question, can this be happening because i was not using a fan??

That looks like nutrient / salt buildup. I would leech in a larger bucket then flush with about 3 gallons.

What are the stats of your source water? PPM, pH. Did you mix anything in the soil? Dolomite lime is a good additive at 1/4 cup per gallon of soil to stabilize your pH. Commercial fertilizers are bad for mj, you would be better off going all organic. Do you know of a farmer that has worm castings? That would be a good start for an overall organic fert.

if you get heat burn your leaves will crisp up in one day and buds will turn pale and dry out.
