Long time reader first time poster, here goes...
My girls have gone really weird, iv trawled the forums for 2 days but im still no wiser. The only thing i can think is either heat stress (the rooms usually about 85) OR somehow iv put my babies back into veg. I have 30 plants in the room and every one is like this.
First 2/3 weeks of flowering looked normal, now they look like THIS-

Your my last hope fellas... thanx in advance.

Have you already checked for light leaks?

well to me that does look like its been overheated, theyll live, as long as you get that temp to around 80 MAX. im not an expert btw mate

 

[MynameStitch]

looks like a mixture of heat and over fertilization.

Hard to tell from pics and not much info, but looks like you have some nute burn and too much n will send them back into veg. Fill out Stitch's form, She's the bomb

neelpeel99, doesn't look like anybody shares my idea that you may have a light leak. I won't bug ya anymore but it would be easy to check. Turn on the lights outside the grow room. Shut yourself inside the grow room and turn the lights out. Let your eyes adjust to the dark. If you see even the most minute light leak, it could be causing you problems.

everyplant looks like it? has to be a light leak

 

[MynameStitch]

Have you already checked for light leaks?

Hey, I did not say I did not agree with you, I was just trying to get more information, but I will agree with you if they are all like that; has to be a light leak.

His plants do look like they are burned as well though.

Hello MynameStitch, I'm just guessing at this point. Yeah, that third pic looks pretty burnt. Good call, you've certainly helped me outta a jam or three.

 

[cork144]

almost looks like a burn i had using straight compost.

 

[neelpeel99]

THanx all of u for your help, the light leak idea got me thinking so i went round last night when the lights should have been off to check and... one of my timers is broke half the lights were still on!!!
Iv checked it and it sometimes works sometimes not so im guessing there fully back in veg now.
Sigh, thats 5 weeks wasted at least i know now.
Thanx for all your help everyone ill give em a lil less nutes as well if they looked burned a bit.
CHEERS FELLAS
