Day 38 with an autoflower strain. Started the run in FFOF. Added grow big too soon into already hot soil. The PMMs of the runoff were at 4000. It's been a week of adding just phed water. The PPMs of the soil are now down to 1300.

We are now in flower and I want to know when is it safe to start feeding flowering nutes. I want to make sure they are getting what they need for flowering but im afraid to over nute them. The girls look good and healthy.
I'm not sure where to start.
Keep measuring runoff ppm until it's lower?
Do a slurry test?
Not too sure where to start?

Personally I'd keep watering and watch for the first sign of major deficiency. Pour the light to it right now in lieu of nutrients.

Ya.... Duno bout that.
While 3gal is maybe bareballs min
5-7gal in soil for auto. Imo.
What does 'for the average auto' mean. Just because they are autoflower doesn't make them all the same. Using too small of a container can limit the size of your auto and make it veg slower/ flower sooner than if it was in a bigger pot. (In soil)

Look at OP's 18" plants for reference.
Also, no one would call a 3gal pot too small of a container. It would not make his plants veg slower or flower sooner. We're not talking about a solo cup.
7gal is an utter waste of soil for a 3 month plant unless grower skill/environment are spot on, even then it's questionable.

My last run defiantly needed 5 gals.
