Autos and Happy Frog Soil

I have 2 autos growing in FFHF soil. They were planted and sprouted in their final home. They are aproximately 3 weeks old.

When should I start adding nutrients? Correct me if I’m wrong, but I believe I should start once the cotyledons fall off?

Thanks everyone!

No sooner than 1 month after the last transplant is a general rule I follow. It can vary a bit based on PPM readings.

I’ve got 2 that are on day 18 from the last transplant and they’ve really accelerated growth in this last week. They’ve been really hungry and I’m going to have to feed them when I water tomorrow since PPMs have dipped. They’ve gone from needing a gal of water once a week to needing it every 3-4 days here recently.
