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. Any idea what my problem could be? will attach pictures asap Thanks in Advance!!!!!
