Hey everyone, I am new to the site, as well as cultivation. I have a few questions on my plants. I'm not sure what my defiency is here, i'm getting crisp lighter green spots on what was a perfectly healthy looking fan leaf. i have 2 week old Stony Creek OG (3x) 1 Arizona and 1 Cheese. The new growth looks very healthy, as does some of the underlying growtth and stems look healthy. this problem occured out of nowhere in about a days time. i watered them with liquid karma diluted 5ml to a gallon and had no problem until i came down to water and the leaves did this as i said, are yellowing and curling and are crisping up. Soil used is Roots Organic, no additives because of such a potent soil to begin with as i've been told. Only thing used besides water so far has been the liquid karma which i was told would not harm plant Light Cycle is 24 on, tonight will be first night 18-6 Room temp is about 65, soil temperature 72 Running Hydrofarm hood Metal halide with 400w lumatek digital ballast Any idea what my problem could be? will attach pictures asap Thanks in Advance!!!!!
