My current grow is on day 48. Been flowering for about 1 week. Growing in ProMix in 3 gallon pots. T5HO lighting. My bloom nutrient is plain Algoflash Bloom. (I know, I will change next grow). Not seeing any kind of harmful nutrient deficiency symptoms. Everything looks really good. PH in at 6.4 out at 6.4 or 6.5. I just want to prevent a cal/mag problem before it shows up.
Got a pic mate?
Not sure if this is suitable for soil (adding to your nutes feed), I don't know this product and it shows a schedule for hydro and none for soil. Maybe someone using this can confirm?
But a foliar spray should be okay (?) but do it earlier rather than later and try not to spray on your emerging buds. If you are only using it as a preventive I would go 1/3 strength and see how it goes.
Cal-Mag def usually shows around week 5/6 you are right in the middle of your week 6.

My 2cents man, hopefully someone using AN Cal mag Xtra will be able to help more.
Good Karma your way.
