First grow!

Girls popped out of dirt 11/9, they have been vegging for a month or so. The first two are the strongest g1 on node 7, g2 node 6, g3, and g4 node 3 or 4, I forget. On g1 I have noticed the brown tip the first leafs that grew razor shaped , i think its called the "true leafs" Also on a set of 3 leaves there is brownish spots present.

First 4 pics are spotings on leaves, the rest are just pics to show you all the progress, FYI: the two biggest already STANK

Any suggestion and comments are greatly appreciated. Lots of pics first showing brown spots, then pics of girls in general.

PS. If in wrong area, I tryed posting in "problems section" but was unable to upload pics.

Looks like nute burn. From what I've read about your mix it has lots of nutes in it. The one leaf burned at the edge would suggest sun burn, but the other with burn inside the margin shows damage coming from inside the plant. My best guess would be that your mix has lots of nitrogen, correct? if so then you have nute burn. The soil also looks extremely dry. I know the instructions for the soil says to let it dry before watering again, this is a bad idea could be detrimental to your plants. Peat moss, when it dries out will actually repell water, then it is very hard to rewet the peat. I suggest that you thouroughly soak the plants, add water so that it drains out the bottom. Wait maybe ten minutes then water the same way again. This could accomplish two things. rewetting the soil and flushing some nutes. My concern with the nutes is that they are in the soil, built in, and you may release more by watering more.
I use a sterile soilless peat light mix for my grows. I add the ferts as the plants need them. this gives me control of feeding. reducing the chances of defficiencies or overnutes should be your goal, not the easiest way for a person to grow while neglecting the plants needs. Not saying you're neglecting.
good luck

you over fed it. sometimes small plants can get burned just by the small amount of nutes originaly coming in the bag. flush it with plain water water it with pure water and it will not spread up the plant. if it keeps moving up the plant it could be a bigger issue. i get that sometimes and its no big deal. once the plants are on there 6 th set of fans yu wont even notice. usually within the first month the lowest 2 sets will come off anyway. i usually chop the lowest set just to let some light get in there. but only the lowest. the one bladed leaf and the next 3 bladed leaf set. but i dont cut em off till a month or unless they crumble up first. just water with plain water a couple times

down the last pic where you can see two little yellowish spots that aint shit bro. when you watered some splashed up on the leaf and the light burned it. thats not from nutes

agreed looks like jute burn. next attempt yoiu should find some coco or some organic fertless soil to mix ide say about half and half.

Thanks for the help guy but i failing to mention, that i do have a gnat issue. Not a real big one, eveyday i peek my head inside the area i notice about 2-3 flying and i kill them. Yesterday I used some buchan pesticide burned it to produce smoke, and over the weekend i will applying some beneficial nematodes. Does anyone think the black gnats larve could have been the cause

Yep, Flush em and lower the ph to 6.0 or they could lock. They are young so don't over do it.

fuckin gnatts suck, but they wont make a plnt look like it was nute burned. if you want to get rid of the gnatts jjust go to home depot and get a no pest strip. i had a seriously major gnat problem id go in in the moring and when i touched the soil to check water level. 90 frikkin bugs would scatter. they did no damage they were just annoying as all hell. the no pest strip killed em off in less than 48 hours i havnt seen one in 2 weeks now. i used to worry to high hell about em till i realized how simple and easy and cheap it is to erradicate them for good.
