I have a plant that looks like its showing signs of light bleaching or heat stress or maybe an outside chance of a calcium def. There is also some nute burn which has been addressed by a rez change today. Been discussing the rest with Weedhound in my log but we can't be sure what to pin the brown spots down to.
Its day 36 in flowering of a 50 day flowering strain so a bit wary of treating it for a calcium def if it doesn't need it & I would find that def strange as I use distilled water which already has a high level of calcium.
Any ideas?
If its just the heat I will deal with it for the next grow but as discussed in my log its not something I can change over the next two weeks.
