JW, "...my serrano is showing some darkening/brittleness on some leaves, it's not just confined to the edges of the leave either. If it were just confined to the lower leaves I wouldn't be too concerned but I see some leaves are effected in the mid section as well." Well, I would be concerned even if it were just the lower leaves. Everything about your plant's appearance communicates to you the state of its health and nutrition. The darkening makes me suspect a phosphorous deficiency. This is what a phosphorous deficiency in corn looks like. I don't have a link to a similar picture for a Serrano pepper. "They are in well drained soil and I feed high quality organic liquid nutes." I have to admit that I am not that enthusiastic about organic nutrients for culture under lights. Do you have an analysis of your organic nutes that you can post here, so that we can determine how much available phosphorous they have? Also, what source of water are you using? I prefer to use rainwater or melted snow. Otherwise you need an analysis of your water supply and you run the risk of salts accumulations from the water itself. Hope you get your digital camera soon so you can post some pictures of your plants. We should be able to tell more then. MM

Hi Kevin, It looks like those lights are surely working! My Penang Peach FINALLY went dormant. I was sad to see the blooms fade and drop, along with the inflo, but I now have 3 tips that are going to make this tree fill out nicely. I have to say that having the HPS light has really helped my plumeria stay nice and healthy. I have noticed that even when there dormant, they are much more healthy than before when I just kept them in the dark cool basement. Andrew

Any plant - succulent or not - should be acclimatized to stronger light. Leaves usually get sunburn marks, don't really fall off (maybe for very young plant) - but there could be another reason for that. We need photo to try to diagnose...

A few plants in my garage. South window, fluorescents on timer + a 1,000 watt metal hallide lamp set to only 4 hours (otherwise too expensive). Temp around 50 to 60 degrees. Nice and chilly = very few bugs and less watering! Oroblanco fruit growing slowly ↓ May be ready by spring? These are the first fruit from a gifted rooted cutting. Key limes ↓ Most have fallen and landed in a key lime pie, which was utterly amazing! Clem-Yuz ↓ More Clem-Yuz ↓ First time this seedling bore fruit! Only a few fruit left to eat! Like a somewhat tart but seedy (10+ per fruit) Clementine. Juicy, easy to peel and full-flavored. A keeper, I think. Not sure it's 100% Clem-Yuz. But who cares, if it's good? Owari satsuma ↓ Fruit all eaten now. So-so fruit quality, but it's a young plant. Armstrong satsuma (photo taken in October) ↓ All fruit is eaten now. Exceptional fruit quality this year.
