I have had a bit of a trawl and found nothing similar if in fact there is a real problem.
Some (Lots) of the fan leaves on my plants in flower, seem to be losing colour to some degree or another.
Turning yellow from the veins of the leaf outwards, the colour slowly draining out until they eventually dry up an drop off. The falling leaves tend to be the lowest on the branches or part net-bound leaves.
This may be natural wastage to expose bud beneath but I do not know.
It will be a while before I can post a lights out pic.
Here a couple of badly adjusted lights on pics for now.Click to view attachmentClick to view attachment Temps have been around 26.4C, RH 50% lights on dropping to 18.4C RH 65% max lights off until I noticed Id knocked the environmental control off. Night temps have not dropped below 23.5C since. RH around 45%. That was between 36 and 48 hrs ago.
How long the fan overide and heater were not working I do not know initially put night temp drop down to autumn weather.
Have seen a bit of greenness return generally but still the yellow vein thing seems to persist.
Any ideas?
Cheers mentiras.
