Professional-grade flowering nutrition for a room running hard
Connoisseur Bloom A&B is the flowering half of Advanced Nutrients' professional base programme, carrying a heavier phosphorus and potassium load than Sensi along with amino acids, vitamins and the pH Perfect buffering system.
Key Benefits
- Heavier PK than the standard range - matched to crops that can actually use it
- Amino acids and vitamins - support sugar transport into the flower as well as mineral supply
- pH Perfect buffering - holds range across a long reservoir
- Two-part control - shift the ratio as the plant fills
- Pairs with Connoisseur Grow A&B - one programme, one grade
Hitting a ceiling in the sizing weeks
In a CO2-enriched room under heavy light, flowers size faster than a standard base can feed them, and the plant runs short exactly when density is being decided. Whether that is worth paying for depends entirely on whether the room is genuinely at its limit - in a two-light tent it is not.
How to Use
- Mixing order: Part A first, stir, then Part B
- Transition: 2 ml per litre of each part
- Mid flower: 4 ml per litre of each part
- Late flower: hold, then flush over the final week
- EC: monitor closely - a rich base plus additives overshoots easily
