Splashing leaves?

Sorry for yet another daft question.... my 2 week old seedlings are already in their final pots. I ummed and ahed and thought what's the point of multiple stressful transplants and buying more pots when I have these pots right here?

But now I read that watering the plants and the liquid solution splashing on the leaves as you water will burn the plants. Watering these huge 15 litre pots effectively and *not* splashing the seedling seems rather difficult! Is this true, even at the low doses I'm giving the seedlings?

If the answer is, as I suspect, "dude you shouldn't have planted them in the final pots yet", please can you suggest what I *should* do in my current predicament?

You don't need to water the whole pot.. remember you're watering for a seedling. . Not for the pot you placed it in.

Growing in coco, I thought you had to water the whole pot until you get runoff so you know it has flushed through, and so you can test runoff ph?

You shouldn't have to test the runoff ph every watering. If you soak that with a seedling your seedling will probably die.

it can.. if theres alot of intense light on.. while your plants are wet.. usually if they dry before recieving the intense light they wont burn.. it depends on what nutes you using too.. because alot of nutes we use can be used foliar also.. so

This is Canna Coco a&b with a third party root tonic. A&B at just under 1/4 strength and root tonic at normal dose. Light is a metal halide 250W that is about 2 ft from the top of the plants. I have a large-ish desk fan oscillating to blow them dry. I just rewatered and even with a smaller can being very gentle I managed to splash them. It's a small space and I'm not very dextrous.
