ISN Nutrients FAQ's
Yes. Supreme Grow A&B and Supreme Bloom A&B cover the base nutrition through both stages, and the six additives handle aminos, fulvics, microbes, potassium, seaweed and cal-mag. You can run an entire cycle without reaching for another brand, which is not true of every range this size.
Most products are sold in 1L, 5L and 20L, with the two-part bases supplied as matched pairs — 2x1L, 2x5L and 2x20L. That spread covers a single tent through to a commercial room on the same schedule, so you scale volume without changing what you feed.
If you are new to the brand, yes. It bundles the range into one purchase, works out cheaper than buying bottles individually, and removes the question of which additive belongs at which stage. Buying piecemeal makes sense later, once you know which parts of the schedule your garden actually responds to.
Fulvic acid acts as a carrier, helping nutrients move into the plant more readily, and is commonly used alongside a base feed rather than instead of anything. It is one of those inputs that does not produce a dramatic visible change on its own but supports uptake across the schedule. Sold in 1L, 5L and 20L.
In coco, almost certainly — coco binds calcium and magnesium, so a base nutrient alone tends to leave plants short. With soft or filtered water, also yes. Growing in soil with hard tap water, you may not need it at all. Add it because the plant is asking for it, not as a default.
