I can tell you it tastes disgusting. Probably not that great for you either.
If you're using it to 'control' PM during veg and haven't cleaned up your surrounding environment... you're usually going to have 'issues' during flower.
Keep your intakes HEPA filtered, eradicate (if possible) any outdoor patches you find with what... I think Eagle-20 is the reigning champ? Don't enter your garden wearing outdoor clothing, don't bring any clones or plants in from outside without treating and quarantining them.
Basically.... understand how the PM spreads and grows and you can act accordingly. No sprays in flower unless it's H2O2... that's the way I always flower, that's the only way to have superior medicinal quality.
