So I'm having an issue at the moment all my plants are growing quite slow, there about three weeks in now.

I'm using canna coco plus with the canna coco A+B nutrient

My tap water EC is 0.3 and my highest nutrient EC has been 0.7 so 0.4 EC of nutrients added to the 0.3 tap water EC

Temps are around 25-26 and the night differential never goes blow 10 degrees!

Here's what I think, I've noticed a weird white mould like build up on the top of my coco and after doing some digging it's alleged that it is salt build up from nutrients, Now I've nearly used them to an extent that they'd build up on top of my coco, However when I mix canna A and B I add one first and mix well followed by the other, could that be the salt build up bearing in mind that both parts form a solid when mixed together?? Could that be why my plants look small and slightly under nutritioned?

Maybe it's because I potted into 20l straight away with out transplanting?

My water and nute ph is always 5.8-5.9 and the run off ph is 6.2-6.3 and run off EC 0.4-0.5 depending on when fed nutrients.

Or? Could it be 1200w LED light being too much however I need the light to keep up the temps

Thanks for reading cheers!

Don't know much about coco I must confess

Transplant time is usually two weeks if your not overwatering
When transplanting into a larger container it will take longer for roots to fill up the bottom but you should see some growth in three weeks.
Besides the slight faded look to your plants they seem fine

The light is not the problem

When you mention your temps are 25 or so hopefully your meeting Celsius
You might be able to lower the light a little and your humidity should be higher than 50%
If you never do a flush you should do just do some freshwater maybe with a little bit of A and B

What kind of light? Ppl think cause something say 1000 watts it's really 1000 watts. Any led that claims to.be a 1000 watt would be my first thought that something don't add up. So your light may be affecting your veg growth slightly. You don't have no salt build up at 3 weeks with .04 Ec I promise you.
Your biggest problem was you went to to big of containers way to quick. You need to up pot correctly. The size if them plants I would still be in solo cups using the sips method....

Ditto what Event said above, pot is too large. I made the same mistake in coco. I recommend repotting to something smaller (1g?) before you go back to what looks like 3g pots.

The larger buckets cause issues of various types for various reasons, and growth is slow. in my experience
