FoxFarm BushDoctor Flower Kiss – 1 Gal

FoxFarm BushDoctor Flower Kiss is a spray-on foliar plant food formulated to be absorbed directly through leaf stomata, delivering organic micronutrients from the top down. It is designed for use during the early flowering phase to support flower development and ease the transition from vegetative growth to bloom.

Why Choose BushDoctor Flower Kiss

Flower Kiss addresses a specific nutritional window that root-drench programs frequently miss: the brief but critical transition between vegetative growth and the onset of flowering. During this period, plants shift energy allocation rapidly and can show micronutrient deficiencies even in otherwise well-managed systems.

• Foliar delivery for rapid uptake: The formula is designed to enter the plant through leaf stomata rather than the root zone, making nutrients available quickly without waiting for root absorption cycles. This is particularly useful when early flower stress is already visible.
• Micronutrient supplementation at the right phase: Flower Kiss is formulated to supply micronutrients that are specifically important during the early flowering phase, supporting flower site development and helping to set the foundation for a productive harvest.
• Stress reduction at the transition: The product is described by Fox Farm as helping to alleviate plant stress during the veg-to-flower transition — a period when changes in light schedule, nutrient ratios, and environmental conditions can slow development if not managed carefully.
• Organic nutrition source: Flower Kiss provides organic nutrition from the top down, complementing soil or hydroponic root-zone programs rather than replacing them. It works alongside your existing feed schedule rather than requiring a reformulation of it.
• Gallon size for commercial and multi-site use: The 1-gallon format is appropriate for growers running multiple plants or multiple cycles who need a reliable supply of foliar additive on hand rather than purchasing smaller bottles repeatedly.

Best Uses for BushDoctor Flower Kiss

Flower Kiss is a targeted additive, not an all-stage fertilizer. It performs best in specific situations where foliar micronutrient delivery is the right tool for the job.

• Early flowering phase supplementation: Apply when plants have just transitioned to flower and you want to ensure micronutrient availability during the initial weeks of bud development. This is the primary use case the product is formulated for.
• Stress recovery during veg-to-flower transition: If plants show signs of stress when flipping from vegetative to bloom — yellowing lower leaves, slowed growth, reduced vigor — a foliar application of Flower Kiss can help bridge the nutritional gap while root-zone adjustments take effect.
• Supplementing a root-drench nutrient program: Flower Kiss works alongside products like Earth Juice Hi-Brix Molasses or other soil amendments to provide a complementary top-down nutrition source. It does not replace a base nutrient program.
• Indoor and greenhouse cultivation: Foliar feeding is practical in controlled environments where you can manage humidity and air circulation after spraying. Flower Kiss is suited to both indoor grow rooms and greenhouse operations.
• Soil, coco, and hydroponic grows: Because it is applied as a leaf spray, Flower Kiss is compatible with any growing medium. The root zone feed type does not affect its application or efficacy.
• Growers pairing with organic root additives: If you are already using organic soil biology products such as Advanced Nutrients Tarantula to support root health, Flower Kiss extends the organic approach to the foliar layer without disrupting your root-zone biology.

Dosing Guidelines

Flower Kiss is a foliar spray additive. The following application approach is consistent with standard foliar feeding practice for concentrated liquid plant foods of this type. Always consult the product label for the specific dilution rate printed by Fox Farm, as rates can vary by formulation batch.

• Shake the bottle well before measuring. Liquid concentrates can settle between uses.
• Measure the recommended dose per quart or gallon of water using a clean, calibrated measuring cup or syringe. Do not estimate by eye.
• Mix thoroughly in clean, pH-adjusted water. A pH of 6.0–7.0 is typical for foliar applications; check the label for Fox Farm’s stated target range.
• Apply to both the upper and lower leaf surfaces using a clean pump sprayer. Lower surfaces have a higher density of stomata and benefit from direct coverage.
• Apply during the lights-off period or during low-light hours to reduce the risk of leaf burn and to allow stomata to remain open. Avoid spraying during peak heat.
• Do not apply during mid to late flowering when dense bud structures are present, as retained moisture can promote mold. Flower Kiss is intended for early-flower application.
• Frequency and total number of applications should follow the Fox Farm feed schedule for BushDoctor products. Consult foxfarm.com for the current feeding chart.
