powdery mildew...don't use any type of sulfur spray in flower.....your gunna have to spray your entire plant

try greencure once a week or hydrogen peroxide every 3-4 days

Are they from seed or did you get a clone...if you got a clone PM came with it

From seed alls it takes is 1 airborne spore to make it into your Grow

Constant air movement...dont crowd your plants together..... low RH...weekly preventative spraying


If you want to keep this strain going...in clone form...get some eagle20 and spray your babies the first week or 2 of veg growth
 
No i haven't, actually i saw some small lil flying bugs a lil while back i started spraying with a pesticide and they seem to have gone away. Only the older leaves have the white stuff on it the new growth doesn't

It is hard to tell. Depending on what spray you used, it can leave residual burns or discoloration. Especialy if it was an insecticide not specific for plants. I get white shit all over my honeysuckle bush outside when I spray the yellow jacket nests on the fence near there. Everywhere that mist touches it discolors and damages the leaves.
Just a theory, but what insecticide did you use?

If that was spider mites you would see the webbing by now, cuz damn that would be an infestation from hell...and never spray your ladies while in flower...rather get some Neem oil and water them with it, I use it as a preventative now cuz it works, I water them with Neem once a month whether I have bugs or not...and I have no bugs, aphids, fungus gnats, or ANYTHING on my ladies, and I have a lot of ladies...lol...My flower room.jpg

this was a wonderful post though and what you sprayed is most likely the problem

If it is PM, it has gone way beyond a little problem, if its spider mites you would see some form of web fiber.

Did the bottle of insectcide have dilution instructions or did you apply it straight?

I'm sticking with the spray as the cause and that is residue or burns.
Try misting some straight water on the leaves and see if washes off.
