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.

Is this sign of over feeding?Few of my babies in vegetative stage are encountering this problem. Some of the leaves are showing like those in photo. My guess is overfeeding the nutrients. But before I making any decision, I want to hear some professional opinions. Nutrient feed interval is per 4 days.

Yellowing/purpling leaf tips outdoors Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?
