Advanced Nutrients Bud Blood

Advanced Nutrients Bud Blood is a soluble powder concentrate designed to trigger flowering transition in the first week of bloom. Formulated with a heavy phosphorus and potassium profile, it delivers a powerful early signal to move plants out of vegetative mode and into productive flowering.

A tiny dose — just 0.5g per litre — means one container lasts through multiple crops. This product works as a transition catalyst, not a complete feed. Its job is the first seven days only; continuing beyond week 1 adds unnecessary nutrient load without benefit.

Bud Blood shortens the stretch phase that occurs when plants resist the light flip, reducing canopy height and promoting earlier bud set. This is especially valuable for varieties or feeding schedules that keep plants growing vegetatively well past the photoperiod change.

Compatible with any base nutrient programme, including Advanced Nutrients, and works across soil, coco, and hydroponic systems. Simply dissolve 0.5g per litre in warm water until clear before adding to your reservoir.

Follow Bud Blood with Big Bud or another bulking additive from week 2 onwards to fill developing flowers. Use during week 1 of flower only at every feeding.
