Maybe you can see the problem better in these two pics, the other pics are the same plant, a mother was taken from it before 12-12. its my cross of c99xblueberryxnl#5

what kinda nutes are you feeding the plant and how much?it looks like nute burn

[shaggytodope]

its gh flora bloom and micro at 300ppm ph is @ 5.7 for my clones wich are the only affected plants. They have not rooted yet, this happened about three days after taking them. the nutes are very weak and I have never had a problem before using this mix. if you look at the pic of the leaf by itself you will notice that the brown spots are localized and the leaves are not burnt at the tip, I have never seen nute burn present like this. the growing tips are dying and drying up, turning black. I sprayed them with a mixture of 2 tsp baking soda in a gallon of water PHed up to 9.0 in case its a mold or something. I just hope its not a bacterial blight or something

how often do you mist your plants?taking another look at the pics i do not beleive it is nute burn.

[shaggytodope]

I mist them every day. They are not under a dome. I took new cutting 1 day ago from a different plant from my patio and now its starting the same crap. This has got to be some kind of disease, I just wish I new what to use to get rid of it. It definately appears contagious

stop misting them it looks like leaf rot from to much misting,i only mist my clones 1-2 times when i first cut them.i had this problem before,when i stopped misting the plants the problem went away

[shaggytodope]

I will try that. They dry out right away though after misting due to the fan in the room, they never stay wet for more than 20 minutes. Peace
