Top buds turning brown and crispy whilst still in flower

[Hotlad00]

HEEELLLPPP!! lol hi guys, got a major issue, my plants are at 8 weeks, and the top colas have started to turn brown and crispy, my temps have have ranged between 15 to 30 degrees night n day, and humidity is around 40% first time ive had this prob. any ideas????
BTW the lower buds seem fine up to now
im currently on a wilma 8 pot, feeding water and mollasses, about 4tablespoons to the 50 odd litres of water in the res
600w light about 1.5ft from the colas

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.

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