lol this is normal, and when i say this im not joking. Within my biology class at school my professor refers ot this as "Death" a cycle plants go through do to light limitations to lower foliage. When the plant grows vertically and starts to produce large fan leaves it shades the lower branches and leaves (round ones you talk about). This cause's the photosynethesis within the lower leaves to be trastically be reduced, cause of shading from higher leaves/branches. And as well all should know leaves do both photosynthesis and cellular respiration to produce food and growth respectively, and when the lower leaves are not photosynthesising enough to keep up with cellular respiration demand they begin to degrad and die. this is known as the Death Cycle in plants, when lower leaves cant photosynthesis (make sugar) enough to keep up with cellular respiration (growth using sugar). sorry for repeating not sure if this makes sense to someone reading lol. This is why lower growth dies. Actually there is a system of measurement for the ability of a plant to have more of a death cycle than others by having larger top foliage surface area then the surface area the plant is taking up. When this is mathimatically figured out a ratio of 5-7 is usually found, every agriciltural plant is based on this ration, a plant with a ratio of 7 means it has a good overall growth with very minimal death cycle, this is good for agriculture so the whole plant developes. Using this system of measurment i have found weed to be near 8-10 with a 4gallon pail and full grown plant. This means that it will have good overall growth but be slightly higher on the death cycle than the 7's. Anyway back to your question, the degridation of the lower circular leaves is totally normal, those are usless leaves onces you get the 3/4 leafs forming. Why keep small usless leaves alive when a plant could shed them to make bigger leaves and produce more sugars to keep up with the cellular respiration demand. If no one knows what im talking about when i say cellular respiration or photosynthesis (blasphemy if you dont know) then please look this up and stop growing till you do you wont regret it

ask for more info if you need on death cycle and ratios
sorry for spelling

Hey BTK3ill
Bagseed won't show you sex until you put it in 12/12.
The droopy yellow leaf is quite normal. Those are cotelydons and they provide a source of nutrients for the plant until it has a viable root structure and enough true leaves to fend for itself. It's death signifies that the plant has exhausted the food it provided and that it's time for light refreshments. As it's still in veg stage you should use very low levels of growth nutes from now.
I think if you take the room temp and then the temp under the desk behind the case you will find that it's warmer under the desk. This is where the case is taking it's cold air from and this area will get warmer as the room temps rise, which they do daily until the end of the summer. That's why I suggested the tube from the intake fan to the side or front of the case where the cooler air is. If you can get some cooler air in there the plant will likely flatten back down. Otherwise another cup of water will probably do the trick. For now at least.
Reread this whole thread as I've covered the ventilation issues in some depth. It probably just went over your head at the time.

yeah i realized the cup of water was really low so i refilled it and it flattened out but i have no nutes... is ok or should i really go to like homedepot or a gardening place to get some?
bagseed has been on 12/12 its whole life, right now i have the blueryders on 12/12 also..
when the bagseed shows sighns of sex should i change the light schedule? and same for the blueryders when they show sex should i then move them to 18/6 or 20/4 ?
