It’s a little hard to see. First up, White Widow…
The lower leaves have these brown spots forming. Is that a calcium deficiency? Do I just get a calcium supplement to fix that? Will it go back to normal once treated?
Second is Bubble Gum…
Maybe not the best photo, but some dark spots are also starting to appear. Is this the same thing maybe?
I have a third plant that is showing no leaf issues.
I am growing in Coco Coir, watering lightly daily if the medium dries out, and just started a small amount of nutrients yesterday. The White Widow was already showing these symptoms before I started the nutes.
800W LED around 0.5m above the plants.
