I am growing about 15 plants indoors under a 600w HPS which have been budding for about 6 weeks now, and one of the plants has small white powder on a few leaves.

I have 10 or so small clones only about a month old which have more of this powder on the leaves and stems, These plants are near my older budding plants.

Any ideas what this is and what to do?

Should I yank th eyoung ones and clip the older ones ?

thank you very very much.

hydrogen peroxide is supposed to work?

also , maybe if I just keep the temp up for a few days it will kill the mold?

i think the mold will flourish in a warm moist enviroment. the peroxide might take care of it, im not sure, i think it would tho. you could go down to ur local nursery or garden center and ask for something to get rid of with powder mildew, i tihnk tahts what its called. get something all organic if they have it, so it wont affeect the plants tht late in flowering. tell em its something ur gonna eat, so u dont want heavy chemicals in it
