So last year all my DLs had thrips. It took me awhile to figure out what was causing bud abort and deformed flowers and it was quite late in the year. This spring I treated them with neem and am now having a much better flower season.
And then I have bud abort again. I checked...yup. Thrips. Can I treat them again now or should I wait until they're done flowering?
I have been removing the spent flowers and putting them in the trash. My Kwanzo and NOID red are toast, though. Not one flower. The others are flowering along happily. Just a dry bud here and there.
