they look a little wet just my 2 cents. make sure you have holes at the bottoms of those cups.. also i would put something around the one thats clear or transplant to unclear container. roots dont like light.

i had just watered them, thats all. there's holes

This is a critical time for your plants, they need to be babied, it appears that some damage occurred to the leaves of a couple of the tender sprouts whether from replanting or the soil caused it.( the soil may have piled up on the leaf edge when watering and caused this damage) When you water try not to pour it directly on the sprouts, it is also a good idea to water just the outside of the container so that the roots will grow outward and downward in search of water. It also appears that you are using a soil with slow release fert's. If the soil contains fert's you will not have to feed the plants for a few weeks, some soils with fert's in them will keep feeding your plants for 2 or more months. Remember dont over water and give em a gentle breeze to strengthen the stem so that the plant will be strong enough to support big buds.

They're growing quite rapidly

I'm thinking these babies are over watered and way to hot. do you have a fan?

yeah. I have one 15 inch and one 4 inch, but i just added the 15'. So everything should be good soon.
i moved the lights a little bit away.

I have them in a new, taller box and its way more ventilated and reflective. ill put up pics, they're doing great!
One even is starting to smell

hell yea sounds good lets see it

Total lumens / sq ft= Amount of lumens per sq. ft.

I have a 2x1 growing space. 2x1= 2 sq.ft.
I'm using 6, 1750 Lumen output CFLs. 1750x6= 10,500 lumens.

10,500/2= 8,756 Lumens per Square foot.
That's pretty good.

My cabinet is 3 feet tall, but I've got a board a foot above the bottom to bring them closer to the lights.
This also allows me to place a fan underneath to circulate air through a hole in the board I put there.
