As for the fertilizer, there has only been a single application of it thus far. When I transplanted the plant I buried it to the exact same level it was before.

I just checked my plant since last night, and the leaves have perked up about 60% on the entire plant. The 3 dark spots however have not changed at all, in intensity / size / number. There as been no increased yellowing yet.

Also- Was it alright that I took scissors to cut off the yellowed leaves at the base?
