I'm trying to discern whether the slight tinge of yellow/purplish brown around the edges of my new phal is a natural response to stress from environmental change (I just brought them home a few days ago) or a response to a lack of light or too much water... orr disease or pestilence related
one of the leaves on the one plant had one small black spot on it that i noticed a couple of days ago.. to be safe, i cut the leaf off with scissors sterilized with rubbing alcohol & applied cinnamon to the cut surface to prevent infection... i am pretty confident the black spot was not any type of fungus as it was harder to the touch rather than soft or mushy ...
right now, on the one plant i am seeing on the underside of the leaves just rimming the edges a slight yellowing ... then taking a closer look at my other orchids, noticed on the other plants a purplish brown edging... it's too soon for me to tell if it's spreading (just noticed it yesterday), but i want to make sure that if it's disease related, i treat it promptly/effectively ... and if it's a natural response to something amiss in the environment, that i make adjustments accordingly...
currently all my phals have fleshy green healthy appearing roots... the two that i just brought home appear otherwise (aside from the slight discoloring on the leaf edges) incredibly robust & healthy... full of buds & blooms... one of my older phals just went out of bloom phase and another is still loaded heavy with blooms & buds... the other two i have are both in the process of putting out new baby leaves... so by all indications my original four are very content... and i would very much like to keep it that way...
please let me know if you can help me figure this out
Thanks!!
