new growth is yellow

[UpstateCanna]

I'm looking for some advice here. Everything has been running smooth but I flipped to 12/12 and my new growth started to come out yellow. It reminded me of a cal toxicity but I'd like to get more input before I go changing things.

Thanks peeps!

Thanks, looks like mag or sulphur def. Either way, an epsom salt foliar spray greened them right up.

Do you mean manganese?
Mag is on the other side of the chart.

I was going to suggest Iron or Sulfur before seeing the pic & trouts post.

Top leaves showing deficient means an imobile element is being affected.

Gotcha. Looking back I see that now. I think I had a lockout issue due to coco being to dry. I watered 2 days in a row and got a great response. I'm debating on watering today,(to make it 3 days in a row) or wait until tomorrow...

You should water/feed coco plants everyday..it a style of hydro growing..you can't over water coco plants,the coco will only hold what it can and the rest will run off...if you don't you can end up with high salt build up, which in turn will lead to lockout of certain nutes...also dont let you pots sit in the runoff...
