Hey guys,
I'm 37 days into flower and 5 of my 20 plants have developed something wrong. 2 of the 5 affected were watered with nutes yesterday, and worsened over night, so I thought its nutrient burn, but they were watered with weaker nutrients than the previous 2 weeks. The other 3 of the 5 affected havent been watered for 5-6 days, so it also makes me think it is not nutrient burn.
The tips of the new leaves are curling upward, which indicates heat stress, but my room has never been above 84, and that was just yesterday, the rest of the time they are kept between 74-78 degrees, so can they develop heat stress in such low temps?
Here are the pics, see the 2 plants on the right that are affected, they are fed different nutes on different days, but they are in the brightest spot of the room.
and a closer shot of the problem...
