Feed, after watering..

Easy with me, I'm a newbie..

So.. yesterday, I gave my plant (auto flower) a gallon of water, not tap, like I usually do on a schedule. I just noticed I needed to include nutrients. Will it be cool to give the nutrients today, a day after giving a gallon of water?

She's in a two gallon pot (soil).
80 days old, from seed.

Thanks!

You can wait until the next watering. Or just lift your pot and see if its light. I've had to water in the am and pm because it has gotten so hot in my area
