If you don't get the help you desire, ask a Mod to move it to the "Infirmary". There is a form you can fill out as well.
First pic looks like a Potassium deficiency. Deficiencies are not my forte.

If brown spots appear its definately potassium deficiency but otherwise its magnesium imo.
As to light height it really depends on your light but I would say most led would be safe at 24 inches. I had my led about 9 inches from my cola and it didn't burn (still not a good idea) if you have height issues bend them to keep them short and bushy.
