This bloom formula is built specifically for autos — plants with short flowering windows that can't afford wobbles. The soft water variant keeps EC stable without over-loading, which means cleaner uptake and less fade halfway through flower. Simple two-part system, no faffing about with extras you don't need.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eDutch Pro Autoflower Bloom Hydro\/Coco A\u0026amp;B SW is a \u003cstrong\u003eprofessional two-part bloom nutrient\u003c\/strong\u003e formulated specifically for \u003cstrong\u003efast-growing autoflowering plants\u003c\/strong\u003e in \u003cstrong\u003ehydroponic and coco systems\u003c\/strong\u003e.

Never pre-mix the concentrates together. Dosage: 2.5–3.5 ml\/litre of both part A and part B. Use a syringe or measuring beaker for accuracy, and monitor with an EC\/PPM meter (Bluelab Truncheon or equivalent) to dial in your exact feed strength.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHydroponic systems\u003c\/strong\u003e\u003cbr\u003eWorks across all hydro setups — DWC, flood and drain, drip, NFT, recirculating systems. Dutch Pro users report particularly strong results in flood and drain with coco mixes.

Autos don't have recovery time like photoperiodic plants, so consistency matters more than swings. Keep your EC stable rather than chasing higher numbers. Monitor leaf colour — yellowing late in flower is normal; dark green with purple stems mid-flower suggests you're dialled in.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eComplementary products\u003c\/strong\u003e\u003cbr\u003eDutch Pro recommend pairing this bloom feed with Dutch Pro Autoflower Grow (vegetative phase), plus Dutch Pro Explode (bloom booster for extra flowering density) and Keep It Clean (reservoir maintenance).
