I have a baker’s dozen clones at about a month old, some of which came off of a plant found to have Thrips. I see marks on some of the leaves of the clones so I’m using Diotomaceous earth sprinkled lightly on top of them. Most thrips stay underneath–that’s where I’ve seen 2 of them on the ‘mother’ plant. But it may still work & the silica is like a nice soil additive for the soil below.
Thoughts or tips? I’m sure others must be using DE for other pests.
