I recently switched to ro water and what i do is 5ml of cal mag for every gallon i make of water or feed. Ro water has almost no calcium or magnesium in it so always add. Its super hard to go overboard with that stuff. Just add all your nutes and cal mag in then ph the water and your good to go.

Which single bloom supplement would I benefit from most?I’m considering purchasing something to boost my blooms. I’ve looked at koolbloom and big bud. I’ve used big bud in a commercial setting and got buds the size of my head, but can’t verify big bud did that. I’ve seen good results with just the GH trio too. Any input is appreciated

Watering question - Volume?Currently doing my 1st grow and had some watering questions. I see a lot online about when to water which seems pretty easy to understand but I have trouble finding the amount of water. Is it based on the size of the pot? or the size of the plant? or both maybe? How much?

Why does coco nutes often only have one A B blend, instead of 2 seperate Veg and Bloom blends?I personally use Plagron nutes in coco, hence I use the same A+B bottles for veg and flower. When looking at nutes for soil they have the 2 different bottles for veg vs bloom. So my question here is why does it seem like some coco lines(plagron, canna) only have 1 over both?
