Hey GC. To start, this isn't my plant, it's a buddies. I've been growing for three years now, and the only problems I've had were nute deficiencies and such. Never had a mold problem, and therefore I honestly don't know what the onset of it looks like, and how early it can develop, etc. Basically, my buddies plant is about a week and a half, maybe two weeks old. It looks quite healthy, has three sets of leaves, is growing at a fast rate, and has a good green colour to it. Well anyway, on the leaves (especially the first set of true leaves), you can see tiny white hair looking things. On the sides of the leaves they are more noticeable (they're still kinda hard to see) as hairs, but in towards the center it looks like a bunch of tiny little whitish dots. So basically I'm wondering, could this be an early warning sign for mold, or could this plant be generating thc already. I would take some pictures of it to show you, but the pictures I did take didn't really capture the white. It's still hard to see even in person, but I can definitely see tiny little white hairs. Another question is what's the earliest a plant starts generating external trichromes? To be honest every time I've grown it's been kind of like a side thing, this is the first year I'm really getting into the technical parts of it. My friends quite worried about this, as it's his first time growing and it's his only plant. Thanks a lot for all your help, + rep to all that respond with viable answers. Happy Tokin -stain-
That's what we were afraid of. Is this going to completely ruin the plant? Or is it still saveable....I'd feel really bad for him if his first plant went to shit already. Edit: I read up on powder mold, and saw that there are a couple different routes you can take to get rid of it. Now my question is, would it be a good idea to use any spray or anything on a plant that young....it's literally two weeks old, and it's third set of leaves are just an inch long. And my other question is it possible for a plant to simply generate trichromes that fast, or when is the earliest point a plant can start developing trichromes? Thanks for all help, it's greatly appreciated -stain-
Update: the white specs and "hairs" are only visible under a very close fluorescent light. I took them out into sunlight, normal houselight, etc. and only under a very close fluorescent could I see them. As I mentioned, I'm not new to plants but new to mold, so I don't know if this holds any significance. Happy Tokin -stain-
The problem must first be positively identified. Then a course of action should be planned. It should all be taken care of prior to flowering. ID it first.
K. Well we'll work on figuring out exactly what it is, and I'll update back when I have a little more information. Thanks for all the input, rep'd both of you. Happy tokin -stain-
powdery mildew is very noticable and very white. pics would help a great deal i have found a great cure for powdery mildew. It's a fungicide gold courses use called Eagle 20EW. PM is a systemic fungus so just spraying the leaves with some organic fungicide or using a sulfur burner will not kill it. It may prevent the PM from preseting itself on the leaves, but it will still be inside the plant. Do not use Eagle within 3 weeks of harvest. It does work very very well.
Does it look like this? Your description reminded me of this that I saw on my plants (not the brown spot, the tiny white dots) : By antigen3 at 2010-05-26 By antigen3 at 2010-05-26 I have a really huge version of these pictures and in them you can see that the little white dots or hairs are just trichs. So if this looks the same as what you're seeing, I wouldn't worry about it. I also have to get the light angle just right in order to see them.
Yeah that pretty much looks like it. Yeah my camera doesn't have the resolution to take pictures that nice. So yeah, thanks for the help, everyone.

The white isn't very noticeable so I've come to the assumption (with the help of everyone here of course) that it's nothing to worry about. But if it does develop powder mold thanks for the product suggestion. +rep'd you guys too. Happy Tokin -stain-
