Powder mildew 1 week into flowering, eagle 20? Switch back to veg?

I have 3 clones about 1 week into 12/12, got them from a dispensary (hmmm) and noticed powder mildew as well as necrotic tips on the lower leaves, as well as lots of general "claw" leaves. Overall, in comparison to the other images Ive seen, they look to be in the beginning stages. I started treating w/ a geranium premixed product called No Powder Mildew, but can already tell it wont be enough

1st question: Has anyone used Eagle-20EW at the beginning of flower? Ive read it should never be used during flower, and that its very effective (since PM is systemic and evasive, I assume it will come back soon after I stop misting my buds w/ other products for fear of botrytis/shitty taste/poisoning)
2nd: Should I switch back to veg since its so early and hit em w Eagle then?
3rd: Does anyone think there's something that's more effective?
4th:Am I fucked?

Im new to indoor have only dealt w botrytis and pests, not this shit
thanks

Id pull them out of veg cut them back . bleach and clean that room really good clean outside of pots with rag . Spray 4 days at least 3 times . to prevent out breaks look into increasing your exhaust.

I agree with posted above, no problem reveging them . also only way to get rid of the claw is feed them just water chill on the nutes for a few , just reveg at least 2 weeks more, and never put an unhealthy plant into flower asking for trouble,

i WAS LOOKING INTO EaGLE 230 EW FOR POWDER MILDEW. THE DIRECTIONS SAY TO USE A RESPIRATOR AND FULL COVERAGE CLOTHING. SOUND PRETTY INTENSE AND $60 A PINT. aND NO ONE IN THE AREA SELLS IT. I'LL STICK TO MY MILK AND ACTINOVATE.
