Light and heat stress, no question. Your light is too close to your plants. you need to move it up/use a heat shield.

cheers mate, weird thing is though the second pic, that bud was pulled off from half way down the cola, the rest further up isnt as bad????

[syanlar]

In that case then I have,nt got a clue, other than some kind of hotspot from the lamp or something else reflecting. May be a disease of some kind but I,m not hot on that sort of stuff. Sorry

Looks a bit like bud rot to me. Especially in the first pic although the colour of the pic isn't that great. If it is bud rot then chop it off your plants ASAP. Also DO NOT smoke it.

yeh i think same as above, did the bud pull of easy????????

^^^^^I'll third that^^^^

Looks as if your RH is way high causing bud rot. Extreme heat or cold multiplies the effect, but it sounds like your temps are pretty well controlled (bit cold at night).

As mentioned do not smoke the buds affected. Add them to your trim and make some ISO with them.........

the swing in temp can cause moisture in the air,try to not let temps fluctuate more than 10 degrees.

[Hotlad00]

yeah they pulled off really easy, no moisture in the room on the black and whiting though

Your light is WAY to close and if its close and 30 degrees thats your issue plain an simple "your cooking them"

[wert]

the tip of the bud looks green still which may indicate that it is not being burned.
what is your rh after lights out this may be the cause ,your daytime rh may drop when the lights come on and the temps rise.
i still think budrot.

[Dredlock]

i understand what your saying but doesnt look rotten to me to be fair, looks brown like a lil rot but still not convinced....looks cooked but we will see soon enough lol :)

[wert]

thats what the forum is all about we give our advice and hopefully we can together come to the correct diagnosis.;)

[THOMAS CHONG]

he saide that the bud pulled away from the plant very easy that normaly means bud rot dont it ??????????????????????????????????

[jobby2812]

As wert said the tips of the bud looked fine so why was that not burnt?

[BuddyBoy]

My sick plant looked and still does look like that, my issue, the thread is here abouts somewhere with pics, was major heat stress, the oscillating fan stopped moving, and blew hot air straight onto 2 plants drying them right out and cooking them, move the light away a bit, and get a heat shield, after my initial heat problems the new sugarleaf growth coming in was green, and still is, and he buds never stopped growing, just my take on things though...

Good luck matey

definatly bud rot, you can smell it rottin, also the root ball is squidgy, think that might have summat to do with the mollasses we been using.
Ah well ill salvage what i can i try again
