i want to say its nitrogen deficiency, but its been getting nutes with nitrogen in it for all summer. its my friend's plant so i dont know every little detail about it. i do know the PH is 7, and they have been putting banana peels on the soil to try to get the yellowing to stop. they have been giving it fish emulsion and some other stuff. the temperature outside has been low 90's to 100's. is it phosphorous or potassium or nitrogen or what? any insight as to what exactly it is would be great. thanks guys. edit: i just noticed in the pics that the leaves are curling like claws. gotta read through the stickies all over again... also, its starting to flower, and its a soil PH tester, which from reading i have found out is bad.
