This is a strain called custard cream, grown in soil under a 400w HPS, using biobizz nutrients.
Currently just hit week 4 of flowering. Within the last week i saw this yellowing appear and it is continuing to progress day by day. I have tried to upload photos of the leaves at various stages.
The yellowing is more pronounced near the light, plus it looks a lot like the examples of light stress here http://www.growweedeasy.com/cannabis-light-burn , so my theory is light stress.
I don't know temperature but there is an excellent chance it is too hot. I also don't know ph, and i know I should start measuring these things.
i have flushed, and moved the light back. I am expecting the slightly damaged leaves to just continue to yellow out and die even if i have fixed the problem. So it might be hard to assess.
