I'm not sure if could I cram all the pics in one post so, here are the rests...
Pic four. Another Phal (NOID). Now this one is scary. The yellow spots weren't there yesterday. I am thinking sun burn, but the other Phals next to it doesn't show any sign of burns. Please tell me its only sunburn (the plant will recover) not that dreadful "yellow plague" (the plant will surely die !!!).
The next pic is the underside of the leaves, its really more yellow than it appears in the pic. I need help specially for this plant. Help please.
Diagnoses, tips, comments, welcome. Thanks.
