Eggplant and green peppers

Eggplant and green peppers

Hello again! Thank you all for the help concerning the seedlings, and i will focus on learning more about damping off and how to prevent it. (this list has been SO much help to me, thank you guys!) Out on our balcony, i have a little garden going, and my eggplant plant is growing a plethora of little deep purple eggplants. How do i know when to pick them and eat them? What's the right length and width? How do i know when they're ripe? Also, how do i know when to pick my green peppers? Do they have to be a certain size? Are the little ones edible? How big is too big? i'm all new to this, and i just don't want to waste food because i'm unsure when to eat it. Thanks! :)
