cannabis problem
    #3081404 - 09/02/04 05:06 AM (19 years, 6 months ago)

I have some problems with my cannabis plants- because of very hot weather it has been hot as hell in my growroom and together with 3 hps lights on 400W each it has been from 28 C in night time to almost 50 C a few days. It has burned leafs here and there wich is so dry you can make powder of some of the leafs. The plant with most damage have maybe around 30% of its leafs burned. I have experienced this before so I know they will be ok but what is new this time is that the leaves are turning upward. They are pointing right up. The plant is also stretchin like mad. its indica and almost 1.20 meter now 6 weeks into flowering with 4 weeks veg time. Bud production is late, I have eliminated all the males and bud development did start after week 3 in flowering but it looks almost halted. I am positive no pollen was released on any females so I dont think its pollinization that causes this late bud development and there is no sign of seeds either. The bud is growing in 40\30\30 soil\perlitte\peat mix with good drainage and are watered daily and given nutes (bio-grow organic nutes) once a week. What can cause that the leaves point right up. Can this have been caused by the heat or is this a nute issue?

another thing that I just realized is that I have a problem with a fan in my ventilation so it has been without proper air circulation wich is also a reason for the extreme temp peak on almost 50 C-

leaves pointing upward can definitly be caused by heat stress. Delayed flower formation is also a sign of heat stress as well. I only have 5 grows under my belt but I have had my fair share of heat issues and I would say that all of your problems are a result from extreme heat. unless you get your temps below 35 C these problems are not going to go away.

yeah thats what i was found out on OG also. I have fixed the fan and turned off the one of the lights for a little while, It has started to get cloudy and the forecast is rain tomorrow. I hope things cools down now. I had a incubator going too hot also :frown:
