How much ec do you guys feed young autos?

Greetings @Patriots781,
Looks like a good start there!
Rule of Thumb for light intensity:
Seedlings: 100 - 300 PPFD
Veg: 300 - 600 PPFD
Flower: 600 - 900+ PPFD
If you can measure DLI, a good range is 20 - 40.
Use the light manufacturer’s height guidelines then adjust for PPFD based on how your plants react.
Hope that is of some use,
-Grouchy
