Yellow under leaves, short stem, help?

Is that something that can usually be found in a hydroponics store?

Oh yeah. Both garden centers and hydro stores will probably have some kinds of guano. Hydro stores will definately have the premixed liquid teas like FoxFarms & others. Many garden centers will as well.

So can it be that stuff that comes in the grow stages or is that totally different cause I was planning on getting some of that also. The micronutrients also made my Fox Farms. It's high in phosphorus and "just the right amount of nitrogen for growth"

I've also seen some things about giving a light mist of club soda on the leaves or pouring into the soil is a good way of giving them CO2. Is that for vegitating or flowering or both? I've seen a lot of different answers with that so any recommendations with that?

ok its good u decided to keep the plant and learn instead of give up on it. first question is whats the soil any nutes in it before u planted or is it just plain potting soil. second i think if u wanna do something simple and succesfull dont watse money on a bunch of nutes and differnt shit just find a reagular nutrient for growing with a 10-15-10 or a 15-30-10 look for one with micro nutes. if u got three sets of leaves shes proabley ready for some nutes at half strength. and just go get some 100 what cfls atleast two but four would be good and a little fan. and water with plenty of runoff coming out of the container. good luck. post some more pics pls

The soil we used is Jiffy's Organic Seed Starting mix. We have another light fixture, 2 feet long, holds 2 F20T12 Florescent light bulbs. 2 bulbs that we have are for plant aquarium and when they are on you can really see a redish tint. The other bulb we have is Natural Sunshine and gives off a blue-ish looking light (looks the same as the dome lamp with the natural light I mentioned earlier). Would these lights be better? And if so should I use both plant and aquarium lights or one of each?? I swear, I did research before doing this, even took notes on Jorge Cerventa's grow guide, you guys just seem to help more with going more into detail about things so thank you!

So when I turned on the light today for the babies, I noticed the Skunk now has little brown spots forming but the leaves are still growing in great lol

u should drop those aquarium lights and just get cfls. the higher the lumens the better. get the soft white for flower and the daylight ones for veg. i promise u will be very happy with better results. are those spots on the new leaves or the old ones?

The lights are working great actually. They are natural sunlight lights. The spots are on the leaves it starts with (not the round under leaves) but they're not on ANY new leaves, the new leaves are totally green but my boyfriend said he may have splashed the leaves a little when adding nutes. Also, I went and picked up Superthrive and Fox Farm Grow Big. My Skunk is getting taller and more leafs so I'm pleased with that. Here are some updated pics of her.

I also forgot to mention that one of the leaves (the middle leaf to form the 5 finger pot leaf) looks as if the tip was cut off or something and has the smallest brown spot, barely can see it. I wasn't too worried about it, should I be?
