Realize that nothing you say or do can help you, only hurt you.
A public pretender is better than you trying to represent yourself.
If the problem is "White Leaf Tips" (as an example).... then you look to the right and see where the "yes" is at. Then look up and it will tell you the deficiency.
Make sense?
Here where I get my guano. To figure out what to use, take a look at the Fox Farm stuff and pay attention to the...
Add enough pearlite so you got about 30% of the mix is pearlite. If you have some mycorrhaize add 1 teaspoon in the bottom of the hole when you transplant.
Don't water on the stem but rather away from the main stem.
Good luck
I've found that a measured 1/4 teaspoon of white vinegar moves the ph of water right around .5 points. If you want, try 1/4 teaspoon and see if you don't get to 6.5 :)
Also, the purple on the stems might be the signal of a lack of 'P'. 1/8 teaspoon of 0-12-1 guano mixed into the soil would help.
I never considered a uv lamp as a source of heat, but of course it does make tons of logical sense. You had approx. 300w within inches of the plant, and we all know what happens when the lamp get too close to the plant.
IMHO, I believe the plant kind of went....ohhhhh uv and then stabilized...
Skunk, you have provided another valuable link for us to consider in a specific way - Cooling of the cell structure!:hump:
The plants responded upon repositioning of the fan, maybe that was it and not the 'stabilization' of the lamp.
Make sense?
The BlakRay is a uvA source and not uvB :(
Photobiological and thermal effects of photoactivating UVA light doses on cell cultures

While near-ultraviolet light has been widely used to photoactivate fluorophores and caged compounds in cells, little is known of the long-term...
The leaves are very similar in appearance to a plant which I have just stuck outside in the high uv levels here.
My leaves are 'tunneling' and also have a 'sheen' on them which was not present indoors.
IMHO, classic overexposure to uv radiation. I'm thinking of putting a piece of cheese cloth...
