When do I start feeding (hydroponics) (autoflower)

Please no advice if you grow soil or photos!

When should I start feeding and at what strength?

DWC, Botanicare nutrients, they have a pretty cool nutrient calculator but I've seen a lot of opinions online about feeding before cotyledons fall.

Immediately, 1/4 strength

I don't have pics my seedlings just popped up I'm sure you can imagine them.


Here's the chart if you're interested, I'm following the expert recipe:

I just did a 1/4 feed of grow and cal-mag to 0 ppm rain water. My ppm is 170. Next week I'm going to go to 1/2. Thanks.

I'd wait to go to 1/2

You're right I'll probably keep it at 1/4 for 3 weeks then move to 1/2. Should I keep the dose to half the whole grow or are they ready for full dose then?

Have you grown before?

Used these nutes before?
