another yellow/brown leaf problem

i apologize for originally posting this question in another members thread. Getting stoned will do that to you. Anyway, my story. Any help would be appreciated.

[FONT=&quot]This is my first grow. I germinated the lone seed that came from a small amount of cannabis that I had purchased at a local dispensary. The plant is growing quite nicely. At about 24” high, I ‘super-cropped’ the plant essentially in half. The top half of the plant was heavy and required the support of a wire hangar to prevent it from hanging past 90 degrees.[/FONT]
[FONT=&quot]However, my plant has started to exhibit some sort of nutritional problem. I checked the ‘sticky’ regarding plant problems and my guess is its exhibiting signs of magnesium deficiency. Can I use magnesium citrate powder mixed in a gallon of water to solve this issue or is magnesium sulfate required? I have both MagCal and Magnesium citrate powder in human supplement form. [/FONT]

Hmm, doesnt look like a deficiency. Check under the leaves for bugs...
