Leaf #1 Leaf #2 Leaf #3 Leaf #4
Yellow edges called Halo-ing Leaf Tear Dying of old aged Birthmarking or
Change in culture
Could be a Nitrogen deficiency
Check the soil pH
Check the pH of your water
The redness could be:
a pH problem
or lights too bright
remove the leaf

Leaf #5 Leaf #6 Leaf #7 Leaf #8
Anyone know?? Leaf Burn? Hairy Leaves Powdery Mildew
or Over fertilization
or PH problem
Could be from cold temps.
Some varieties are more hairy
Could be mites
check with a 30x lens
Increase air circulation
I use PHYTON 27 to cure

Leaf #9 Leaf #10 Leaf #11 Leaf #12
Bleaching? Birthmarking

too albino after being
too cold
Remove the damaged leaf

Check for mites
Too much light
Too much fertilizer
Its a Nutrient problem
Seems worse on Capillary mats (Travis)
Leaf #29 Leaf #30 Leaf #31 Leaf #32
Brown spots on leaves
Burn spots?
Wilting leaves Leaves too White or Yellow Missing green/streaks or "lighting strikes"
1. Condensation forming on the leaves
and then "burning" the leaves in the light
(turn brown if I have them in an extremely
humid environment)
2. Fertilizers can cause ugly spots as well
3. Maybe fluoride or chloride burn from
city water?
Heat Stress (in Summer)
could also be Root Rot
from too much water

1. Too Much light.
2. Lack of magnesium
Add some Epsom Salt to the water.

Caused by servere neglect and allowing
to dry out. Once the plant is rehydrated this
pattern may show up.
Remove these leaves and keep the soil moist.
Leaf #33      
Missing green/streaks or "lighting strikes"    
Caused by servere neglect and allowing
to dry out. Once the plant is rehydrated
this pattern may show up.
Remove these leaves and keep the soil moist
   


Birthmarking is actually the leaf sporting of the red back
- it's "red gene" is randomly turning on at random places

Change in Culture could be letting the plant go dry for
and extended amount of time

Leaf Stain is like Birthmarking

PH Problems normally a PH problem will show itself over more than just one leaf,
- so if just one leaf shows the problem it's not a PH problem, normally

Too Much Light, set your timer for less time, and/or move your plant further away from light source
