Incorrect. Bt is used to keep worms from developing in their nesting area. Their nesting area are the buds themselves. During vegetative growth there is no place for the budworms to develop (hence also the reason people call them "bud" worms).
Bt is completely natural. It is truly an organic substance found naturally in all soil types. You can safely use either spray Bt or powder up until harvest, although if you use powder you may have some present in your buds at harvest. In over 50 years of usage there has never been any reported human toxicity due to Bt.
I hope this helps and if you have any further questions on Bt feel free to ask. If I do not know the answer I will tell you so and not give you incorrect information.
I have just heard with BT that if you use it late you can taste it sometimes. Im not organic but I like to go pretty basic when it comes to nutes and such. Thinking at this point im just going to ride it out and just examine carefully everynight and remove anything suspect. Thanks for the imput guys.

yep. use 1 tsp/gal and drench your buds. I find any more than 1 tsp/gal earlier in bloom will cause brown hairs.
Make sure you do it on a warm day so the buds don't stay wet and mold.
Likewise, you can use plain water to rinse off the buds a few days before harvest.
if you're 2 weeks from harvest and the eggs were laid recently (meaning you haven't seen a single caterpillar or egg yet), then they won't hatch in time and grow fast enough to do much damage to your buds anyhow. Generally moths will lay only a few eggs per cola / plant because they don't want to overcrowd their young, though if allowed to hatch and grow they will quickly destroy your bud.
The eggs are white, tiny and round. They're fairly easy to spot, usually are stuck on a leaf, hair, calyx. Examine some buds closely and you'll find a few. I crush the ones I find with a tweezer.

What concentrate of the product do you use, my BTK label says 3 ml per liter? That would be half strength with the stuff I have. Will it still work that weak? Thank you.
