I use five gallon fabric and air pots and don't water until weight gets to within 1lb. of dry weight and keep 1lb. below wet weight. In that 5-7 day time frame, I moisten the upper layer when dry with a 16oz. squeeze bottle, radiating out from drip line. Not for all, but in my grows, water by weight removes the many watering too OFTEN problems common in these threads.

Why is a 9 day old seedling in a 3 gallon pot? You are practically asking for watering problems by using a pot that is too big for the plant size.

I start with a pot that weighs 150 grams dry, then transplant to a pot that weighs 400 grams dry, then 1200 grams dry, until finally I end up in 3 gallon fabric pots that weigh 4000 grams dry. I use a scale to weigh the pots to be sure I don't water too soon.

If you use a pot too large, then you cannot water properly because if you soak a 3 gallon pot with just a seedling, that pot will still be soaking wet after 5 days. The pot needs to be small enough to dry out, otherwise the roots will never get enough oxygen. When you water to soak the pot, you are actually forcing fresh air thru the dirt, after the water dries out there is fresh air left. If the roots never get air, they will rot, or at the very least they will retard new growth.

You need to use pots only large enough for the plant to use all the water in 4-5 days, and replant as needed. You will be rewarded with fast, healthy, vigorous growth. Do not make the mistake of starting with your finishing pot.

Autos like being planted in their final pot. Ive done it successfully in 5 gallon fabric pots and it makes things pretty simple when you get the routine down. But photos out perform autos in so many ways, i will never grow auto again.
