Is There A Dr. In The House?

so maybe i'm being paranoid, but this is my first grow, and i'm trying hard to make it a good one. i'm growing nirvana's short riders. they're four weeks in soil and growing like crazy. about a foot tall already. they don't seem to be suffering, but i want to make sure i'm not heading down a bad road. they're growing in fox farms ocean forest with a little vermiculite mixed in and under 20,000 lumens of cfl light, mostly 2700k at this point. i just started feeding them at the beginning of their fourth week. pure blend bloom every watering (roughly 48 hours) at 1/8 strength. a few of the leaves are getting spots on them, and the edges are a little rough looking. all of the new growth and most of the old is fine though.

looks like powery milldew, does it wipe off, if it wipes off its milldew(use 1/9 no fat milk water)
if it doesant wipe off ,"gnats"

That doesn't look like PM to me. Look under the leaves for signs of bugs, ie. eggs, mites, webbing etc. Except for the couple of little blemishes, your plants look really healthy. I wouldn't sweat it too much.

have u got a close up pic of pm, my RIU plant prob pics dont come up any more , after they upgraded the sight
give us a link please

nope, doesnt' wipe off, but i didn't try the milk formula, just a little distilled water. i'll try it later tonight. the leaves almost look a little thin in those places. would that sort of mildew eat through a leaf? a few of those spots are more brown-ish... nothing under the leaves to suggest bugs. haven't seen anything either. they seem to be pretty heathy, i just don't want them to go south in a hurry. better safe than sorry i thought... i didn't give them any nutes this watering. seemed like 1/8 evry watering was pretty light though.

is there any little things running around on soil, tap the side of the pot , they like to hide

I know this isn't an MJ plant but it is a good example of what it looks like. I battle it with a couple of my rose bushes every year.

thanks mate

No problem.

thought i'd post up a few better pics. don't think it's the mildew after seeing the pic of the roses. thanks for the input so far, btw... they're officially 4 weeks in soil today.

the plants are very healthy, don't even look at it, its nothing
water marks from fola spray, most likely

you can see the blistered edges around the yellow spots on the leaves. its probably from water left on the leaf after watering that magnified the light from the cfls and burn a scar into the leaf.

good info. thanks... i'm a new daddy and i want the best for the kids. lol they're over a foot tall now. i'm very happy with how things have gone so far, and really eager for when i can sit down and enjoy the fruits. lol
