Anyone can link me to a canna grow chart for coco + autoflowers please!?
Hi Kosher - I don't think Canna have made a schedule for Autos yet - their grow guide on the site is for photo periods.
you can find it here and tailor it to your medium and res size (for me it's a 5 litre bottle where i mix my nutes)

I'd half (at least ) their figures and see how that goes for you! At late flower (day 70) with all nutes mixed my EC is coming out at 2.1 (including background ec .. not including PH down)
