Sorry for all the bother. Let me try to explain in a bit more detail and with a couple of pictures. 4basjoos about 2ft and 2 namwah's about 18" high or so. They are under 400 watt MH bulb and in a south facing window. Originally they (Namwah's) had grown to about 12" from the light so I lowered them now they are about 2ft or so undet the light but still in the window. I have the bulb on at 12-8pm so they are getting light from the window and the bulb and then the bulb only after sunset. My shed is heated to around 70degrees and I have a cool mist humidifier on the floor and a seperate humidity gauge on the other side of the room which is reading about 60% humidity. THe namwah's were putting out at least a leaf a week and were doing great until about a week and a half ago. The leaves looked a bit droopy but nothing otherwise. As stated before my natural gas heater was blowing on them so I blocked it to prevent the heat from directly being blown on them and that is around the time I noticed the leafs droop. I did this because I read somwhere that the hot air blowing directly on them is not good. After that I again let the air blow on them and they looked a bit better. 4days later or so I noticed that the last leaf that was fully open was getting a dry spot in the center of the leaf. 2 days later it was totally dried out in the center. This spread to a couple of other leafs and now the one that just came out looks more "clear" less greeen more clear streaks in the leaf and now that too has brown dry spots. I looked carefully at all the leaves and some appeared to have black specs and upon more research I thought they might have spider mites. I purchased a product from the store called CONCERN insect killing soap. The main ingredient was neem seed oil. It is mixed 50 to1 and I only applied it 1 time, yesterday. It does say that you should wipe the leaves after the 3rd application (only once a week) due to the soap in the product.
I forgot to mention I was watering 2x a week because the hot air was blowing on them directly and the soil was drying out. I have miracle grow soil and was adding miracle grow once a week or so to the water. Maybe burning from the miracle grow??
The leaves on the other namwah also look a bit droopy now too.
Photos are in my gallery thanks.
