Question on watering after Transplant

I have 10 Ak-48 that are 3.5 weeks old and I just transplanted them 3 days ago. I had them in 10oz. cups and i just transplanted them to 1 gallon containers. I am using foxfarm ocean forest soil. I only gave each plant 20oz of water when i transplanted them 3 days ago because I did not want to over water them. I was wondering if I should soak the whole container when I water tonight or if I should just give it like 20oz. again? Also, I will not need to add nutes for 2-3 weeks using the Ocean forest? Right??? Thanks

I am also using Foxfarm Big Grow and Bloom, just have not started using them yet.

Read the plants, do they look like they need water, are the pots light in weight, if so water them, if not leave them be.
I would give them nutes 10 days after based on plant growth and how they look.

But how much water do I give them? Do I give water until some water comes out the bottom or do I just give them alittle water still because they roots have not grow that much?

When the medium (in my case soilless premier pro-mix) is dry like 1 inch from the top and the pots are light i just drown them until water comes out the bottom.
It's fine unless your medium doesn't drain well....

I usually don't water to the point where it drains out the bottom. Err.. say 'good bye' nutes!

I usually water as minimally as possible. You can always water some more.... But it's really fucking hard to get water out of soil!
