    Default Bud Blast and Fertilizer Burn

    Is there a connection between bud blast and fertilizer burn? I have an Oncidium Twinkle that currently has five flower spikes, and about half of the buds have blasted. This plant also has blackened or browned leaf tips on most of the mature leaves. It receives the same amount of fertilizer as my other orchids, weakly weekly been in growth or blooming. I've had this plant for about a year, and I have not yet repotted it. I have several other orchids in bloom right now, that are not experiencing bud blast or burned leaves. I would think that if the leaves and roots are being damaged, then it's going to be difficult for the plant to bloom successfully as well. I'd like others' opinions on this.

    Sorry to hear that. A picture of the plant would help to ascertain the cause. fertilizer burn could be one of the reasons for bud blast but there could be other reasons as well.
    some of the them are
    a) thrips
    b) sudden drop in temperature or humidity
    c) does not have sufficent energy to sustain multiple spikes.

    Matt, get out your magnifying glass and have a look at the thrips threads!! "Blast" can be "sucked dry." Lost half my phals blossoms for 2 years now...

    I don't think temp or humidity are a problem in my growing set up. I'm got them both pretty well regulated. I might have to worry about these thrips though. Perhaps I should take a look at these little buggers.
