Athena Nutrients FAQ's
Blended Line arrives as a liquid; Pro Line is a dry powder you mix yourself. They cover the same nutritional ground, so you are choosing logistics, not a different programme. Liquid is easier on a small tent. Dry is far cheaper to ship and store, and a sealed bag keeps indefinitely. Pro Line is usually the one people land on once they are feeding a full room.
Balance corrects pH and adds calcium in one pour, so you can leave a second bottle off the bench. That pairing is useful on reverse osmosis or soft tap water, because those waters are already low in calcium and usually need pH correction. It is not a full Cal Mag replacement in every setup, but it cuts how much extra calcium you have to add.
In coco, almost always — coco binds calcium and magnesium, and the base nutrient on its own often leaves plants short. Soft or filtered water is the same story. Soil on hard tap water can be fine without it. Balance already contributes calcium, so look at what you are already adding before you stack another bottle.
Fade belongs at the end of the cycle. It is written for the last stretch, when you stop pushing growth and want a clean finish. It is not a plain-water flush — use Athena's own schedule for when to start it and how long to run it, rather than swapping it in as a stand-in for the last feed.
Liquid bottles are 0.9L, 3.8L and 18.9L — the metric versions of the US quart, gallon and five-gallon sizes Athena sells elsewhere. Dry Pro Line is bagged at 4.5kg and 11.3kg, and there is a Mix Kit of three 0.9kg sachets if you want to trial it first. A drum tap is stocked for the 18.9L drums.
