I can't take pics right now but will give you whatever info I can.
Outdoor, started from seeds, transfered to earth 10 days after they popped up... just used miracle grow in the hole. Watered as needed, once every week or so using liquid miracle grow plant food, and since budding bloom booster once a week.
Last week a lot of leaves started yellowing, and now almost the whole plant is yellow. New growth is green at the base, moving to yellow toward the leaf ends. Some of the yellower leaves have black/brown spotting and come off the stem easily.
I have been trimming (hand plucking) fairly irregularly.
The others do not share this problem, and all were treated the same way. The only odd thing about this one was that it was under a street light sort of thing that used to come on when it got dark. Once I realized that this might be why this thing was budding late, I killed the light. It stands to be the best of the bunch, except that I am afraid it is dying.
Any help would be greatly appreciated.
