ok well i cant really help you on the bug problem but i can give you a few pointers on some things to fix
1. you should never put more than one plant in a pot, cup or anything used for planting they get rootbound and start to kill eachother
2. you will need alot more light for 10 plants than one cfl and i would turn the cfl(s) on thier side; thats where most of the light is
3. lose the tinfoil and use mylar foil causes heat spots
4. the plants are too young to need any plant food give em some time before you feed them
The best of luck to you and your grow man:thumbsup:
