I give it about 3000 lumen per sq foot but I keep it mainly out doors on my roof. I supplement the light for the evenings in an open air room with like I said about 3000 lpsf. For Ferts I mix 1/4 teaspoon of Flora-gro, 1/4 teaspoon micro-gro and 1/4 teaspoon flora-blood per 2 gallons. I water it normal once a day and water it with nutri about once a week to get it flushed. I have cut back with the nutri though and now just spritz it with Magnesium Phoshate, mag carbonate, and potassium mag. I figured the yellowing orignally was from lack of Mag and maybe Nitrogen. I never let it get into the 60s range in temp and never too hot. If my medium seems too warn I put a towel around its base and under it. For humidity it is at normal Texas Humidity, which is to say a good chunk in the summer. When it comes to over all coloration it now is a nice healthy green but the coloration is fading from the tips of the leaves in the brown to yellow rnge. The leaves are also slightly curling under. I even give it c02 once a day if not more. Thanks for your help.

p.s. How do I add a pic? I took some but see no upload button.
