Neptune’s Harvest 2-3-1 ok?

always difficult to know with soil.. try to give a well-rounded diet and react to what you see in a conservative way -- don't let OCD cause you to jump-the-gun and add more stuff when a slight problem arises. If you move it outside, expect to have to acclimate it to the new intensity. It may require a shaded area and only 1-2 hours initially... watch for wilt. It will look incredibly unhappy, if it is too intense. you can't miss it. Remove it from light immediately upon any sign of wilt or droopiness. sorry i can't help with the organic side of things.

What's your lighting schedule inside like vs the amount of daylight outside right now? If this is off it can cause your plant to flower early and then reveg. slowing down your growth. I'm not positive this is also true with auto flowers but I would guess so! But I also think they would benefit and grow bigger in an 18/6 cycle indoors. Happy growing!
