My plants are starting to develop a problem. The bottom leaves are lightening up to yellow spots and then turning to dark spots... it looks like the leaves are dying. Any suggestions in what the problem might be? Possibly a magnesium deficiency? They have been in flower mode for 3 days, but this started before flipping from veg. There is still new growth at the top. Any ideas of what the problem is?
