First are you 500 or 700 cal for your ppms.
the reason I ask is that I feed daily at 1.2-1.4ec. That’s about 600-700 at 500cal and 850-950 at 700cal.
I only use a DUTCH PRO hydro coco GROW a/b with added Ca.
feed every day at 1.2-1.4 with pH around 5.5-6.0. As long as it’s within this realm I’m happy.

I’ve only got 2 under my 400w for now and one is an auto.
not sure how long into flowering. Maybe 4-5 weeks of 12/12.
I don’t really count flowering weeks etc any more. (Been growing for 11years) just grow then until they’re ready.
