Variety: Permafrost
Medium: Black Gold
Nutrients: FLD 3 part Late veg mixture
Temp: 85F to 89F
Recent changes: Moved into other room and placed under HPS & MH mixture Ratio: 1:1 instead of straight MH
Light cycle: 16/8
Problem: The second day after moving under HPS/MH mixture and the first day after feeding just like we have been feeding them for several weeks, about 2/3 of the way up the plant, on different branches of varying age, suddenly we got about 10% of the fan leaves only in a narrow band around the plant yellowing along the edges and then stayed the same for 2 more days.
The effected leaves aren't getting any worse of any better and it is not spreading to any other leaves. The leaves feel just like the healthy dark green ones next to them.
The first picture is of the biggest leaf effected while still on the plant. The second picture is approximately 90 degrees around the plant at the same height and is the second largest leaf from the third picture which is of 3 effected leaves picked and laid on white paper to better contrast. The pictures on the plant were shot in a 50/50 mix of HPS & MH light without flash. The third picture was shot under incandescent light with flash. The leaves in question in the first 2 pictures are slightly below center of the picture. The ones higher aren't actually turning copllor -- it is just the way the HPS light is hitting them. The one in the ceenter of the first picture is actually the best one.
The leaves are NOT curling or drying out.
All of the nutrient deficiencies that I read about involved curling leaves and implied a more wide spread distribution in the plant.
The other 4 plants that were moved with it and feed out of the same batch of nutrient mixture are doing just fine even though they all 5 had even thing done as closely to identically as possible. However the other 4 are a different variety.
What do you think is going on and why are the effected leaves in a narrow band around the plant, even though some of them are twice as far from the junction between the branch and main stem as others?
Any insight you can give will be appreciated. Right now it doesn't seem to be a crisis because it isn't getting any worse.
Thank you and great smoking everyone.
