Hey guys just curious if this is some kind of heat stress? I have four plants that I have just brought outside to start flowering three days ago. They were under a 600w mh. Its only 28-30* outside and today is semi overcast 65% humidity. There last watering was three days ago and they are still...

So I'll give a brief backdrop on my scenario to give some contributing factors to what may be wrong.

Hey guys I'm late into flowering and the buds are starting to lose their smell. I think it's heat and light stress. One of the buds close to the light just shriveled up and died. The others are doing OK but ripening at different speeds, or starting to smell like fruit?!! Should I just cut my...

A tent of a friend of mine is now 8 weeks into bloom and some buds start to get extremely yellow bleached. It must be that they're too close to the HPS lamps because it only appears in places directly towards the lights and only on budsites that are quite close to lamps (and maybe some...
