With a 30X lens look at the under side of the leaf for bugs.

Could be pests for sure, but what kind of soil are you using?
In decent soil like FoxFarms Of, that's got nutrients in it, you still got to start adding nutrients after about the end of the second week.
If your soil has no nutrients in it, you should definitely start feeding her.
Where do you get seeds from LineageGenetics? I might want to try some of them.
GirlScoutCookies are fun to grow, after they get going. Mine were kinda slow in the beginning few weeks, but they turned out fine, great smoke.
GoodLuck with yours.

Thank you for the replies. I will get a lense and check for bugs. I didnt see this on the other plants and they have all been in the same tent for about a month so assumed it was not bugs., but it really kinda looks like it! I will let you know what i find with the 30x.

I cant remember the name of the soil the gsc's are in, but it has no nutrients in it. I will try and post later tonight the name of the soil when I get home. The two scrog'd plants are both la confidential and are in Fox Farms of. Good tip on adding newts as I have just been feeding them pH water and it's definitely been two weeks.

the gsc has gotten connissuer grow part a/b at the level of 1ml/L for the first couple weeks and then recently upped it to 2ml/L, like i mentioned above the soil they are in isnt soil but a substrate with no nutes. It looks like soil kind of. They are in 3ga pots, doing 2L of water per plant about every 4-5days. There is some run off, maybe 10-15%.

the GSC with issues is the one in the bottom right.

I had spidermites on 3 plants, gnats on several others, and aphids on another, all in the same room. The bugs seem to like certain plants.
