HELP, crispy brown leaves??

can i have your opinions on a problem i have, my plants leaves are turning crispy brown, and more or less crumble in your hands when touched. i know the easiest way for me to show would be a picture, i tried this but you carnt see very well with the picture.
they actualy look like burnt off the lights but lights are a ft from the buds, so there well clear, plants are three weeks from harvest, buds are still white, so there not browning off yet, plants are in 15litre pots of coco, any advice would be apreciated, cheers

Don't have enough information to really advise anything else. Good luck. :)

i have managed to get pictures of my problem, BUT to large to add on here, dont know how to resize them, but have somehow managed to add as my aviator, so any comments?.

Just from that small photo they really do look very, VERY unhappy.

Answer the questions in this troubleshooting forum and then perhaps one of the "growheads" here (I love that word :D) can help you figure the problem out.

get a free program called pixresizer and resize the pics, when you start a therad or reply scroll down to the Additional Options section and click on manage attachments in the attach files part then browse and find your pics


hope this helps

Those look SCORCHED. HAve you been overfeeding them?

Stinky.....blight?

Hm.. I'm not aware of any 'blight' type diseases that you'd commonly find on cannabis. Like, viral type. I'm thinking fert burn plus high heat on that one. pH problem could contribute but it's #3 on my list, and until the OP gives more info, it's a big ???

finally got a couple of pictures sorted, now this has only happened in the last week, with three weeks left until harvest, feed and ph levels seem ok, i have done nothing different all the way through the bloom stage, only started adding boost for the last four weeks. temp is 88f but does creep up to 90 for an hour or two later in day. and my whole crop is going like this.

Well here'd be my guess...bloom boost overdose.....major league. I'm only saying that because I'll bet your plants were doing fine before it and now look half dead. And ARE half dead I think. Whatever the last thing you "changed" or "added" and then your problems started is where the problem lies. And I'm thinking its the bloom boost.

What to do? Flush. Do you have something like FloraKleen? If not then straight ph'd water and that's all. If you leave them as is you're most likely going to have a bunch of crispy nothings in a few weeks. You may feel free to disregard this advice (please...... because I have a feeling those may very well be done already.)

I cannot offer you any more tips since besides the photos and the mention of coco I can't get much more info out of you except that "the levels seem ok" Without some clear numbers and names of what you are using. I'm just too afraid to guess.

Good luck.
