Looks to me exactly like the hear stress I saw in my outdoor lady last year.. 30 or higher is just too hot with them.. Especially if the humidity gets lower. A fellow grower Mrs_larimar turned on to this Chart.. http://www.just4growers.com/media/23631/vpd_2degree.gif .. lovely visual representation of what the plants need are.

If you have issues reading the chart... It basically says optimum Humidity of 60-52.5 rh is ideal for healthy vegetation in late flower with a Temperature range of 30 degrees Celsius. Try to move it to a more shaded area that still gets an average amount of sun.. Again it's a wonderful chart and I hope this helps.

2 Yellowing Fan Leaves I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

Yellowing, burnt tips and edges Hello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help
