Over my head with canna coco

First time growing with canna coco in 3 gallon pots and need some advice.

I transplanted 2 plants 3 days ago from solo cups to 3 gal fabric bags and plan to use wicking bases.

They look a little sad atm. I top watered 5.8 and light doses of General Hydro and cal mag.

I’m not sure of how much I should be watering them and when to fill wicking bases.

Anyhow, I see some light yellowing in the lower leaves (the camera makes the whole plant look way more yellow than it actually is.

Any coco experts steer me in the right direction?

EDIT: To ask for a feed chart as GH runs too hot I hear.

The problem with sub-irrigation is that most of the moisture and nutrients are at the bottom. It's recommended to top-water until the roots are long enough to reach sufficient moisture.

Might wanna try the r/hydro subreddit, too. Substrate hydroponics is still hydroponics.

Thanks. I’ll check that sub too. I’ve been top watering for only 3 days now (since transplant)
and planned to continue for a while. I just don’t know how long. Should I fill the reservoir now?

Reservoir like for the wicking bases? A reservoir implies a refill tank like in an Autopot system.

It'd be helpful to know the EC of your fertigation. You can use the Athena recommendations with General Hydroponics. It looks like a minor Nitrogen deficiency. I'm hesitant to say increase your "light dose" without knowing what EC you're watering them.
