What the hell is this ???????

so this is what happened over night. The weird thing is that this happened on only one side of the plant.
this plant looks healthy otherwise. she is in the 7th week of flowering.

any advice what this is and how can I fix this problem?

burn spots maybe, raise the lights.....

last time you watered?

thats true that I have 4 BIG cfl`s on that side, but can look this bad???
will this affect my yield?

i grow hydroponic so she get feed 3 times a day

do you mist your plants??

the brown spotting could be burning caused by magnification of water beads setting on the leaves.

looks like you have excessive salt build up in your res casuing lockout- that spotting could be calcium and the leaf twisting is usually P nd the dead edges is usually K. when was the last time you draind and refilled that res? ph ok?

i change the water and solution from 5 to 5 days. the PH is between 5.5 and 6.2
what should I do now? how can I fix this?

come on guys....come on ..... im freking out over here

like....nobody knows how to fix this????

anybody has any idea how to fix this??????????????? please !!!!!!!!!!!!!!!!!!!!

you cant always repair a plant 100%, to me it looks like everyone's suggestions so far combined into 1 problem.
If your resevoir is ok i would move the lights, with 4 BIG cfls could have 1 on each side, not 4 on 1 side. If it did happen to be a nutrient fluctuation or nutrient lock-out i would suggest soil for future grows. Brings out subtle flavors you cant experiance otherwise and is also very forgiving with nutrient fluctuations. Looks good other than the spots though, do you know what strain she is. 7 weeks into flowering and still pure while pistols? Gotta be heavy in the sativa genes i think >_<

what kind of system do u use

Ok first of all, take a big rip off a bong and let it out slowly......ok here is the bad news......it will not be a quick and easy fix, sorry but you will just have to try each thing at one time. Ok first check your nutes! If it is only half the plant then I would guess it is either bugs (get a microscope to check) the salt from the spraying on the leaves, or what BisGrow said. Ask yourself what changed in the past few days and could that of been the cause. if its the lights being to close then did you move the lights? or did the lights move themselves? sorry I'm baked, course the lights didn't move but it looks like you are in flowering so if the weight of the buds are bending the plant then it could be heat spots from the lights

Dude if its 7 weeks into flower could just be the leaves turing brown with the finishing part of the plant's life. Leave them on the plant if its not a bug problem so the buds can soak up the nutes and finish out nice

for some reason this didnt even occur to me, the bud weight deffinately could have dipped it too close to the light over night.

1. yeah, is in the 7th week of flowering but still needs prob another month. she s a huge sativa

2. i didnt see any bugs. I have two plants in the same closet and they been alright the whole grow except now and is not even 1/2 of the plant . there are only 2 branches and the leaves that have those spots are kinda close to those big CFL. So than, i think is the lights.

But is it possible for CFL`s to do that? i thought that the CFL`s are ok from this point of view.

otherwise, this is how this pant looks like

do you have any idea of what your ppms are? Also what strain are you growing, based on the pistils and the swelling of the calyx's it looks like you may have a few weeks to go until they are mature.

I do believe it is salt buildup (over fertilization) like smokeybandit said. Also one thing I have experienced first hand is that when lights are intense on a particular part of a plant while there is excessive or close to the max amount of nutes a plant can handle, the parts of the plants to first get hit are the ones where the bright spots are from the lights, I've seen it first hand several times. So this is why it is a coincidence that your plants are doing this on the side where you have extra cfls shining.

Lower your ppms, or just give them plain water for a few days, they are saturated with nutes anyways so don't worry, but still adjust the ph. Also Move all lighting away from that side and on to another area of the plant and distance all your lights firther away, not to drastic but just give them some reprieve from the intensity of the lumens. I believe this should help your situation get back on track

i have no idea what my ppm is. i have nothin to measure with. as fo the lights....it is impossible to move them further because of the space
