Well the bloom product I see in the image is from Dyna Gro and it is meant for when the plant is in flower.
BLOOM™ 3-12-6 is specifically formulated to be used during the flowering stage. Begin using BLOOM before your plants decide to shift into the flowering phase.
- A lower level of nitrogen will help reduce stem elongation and invigorate cola zones (budding area) to promote dense, vibrant flowering buds.
- High levels of phosphorus and potassium push production of resinous, potent and sticky flowers.
- When applied, the plant nutrients in BLOOM are immediately available, giving your plants the ability to access all the minerals they need for optimum production.
- Ample levels of calcium, no need to supplement with a Cal-Mag product.
- Use with either complete base nutrient Foliage-Pro® or GROW™ to regulate nitrogen levels for best quality and quantity.
- Excellent for all indica, hybrid, and sativa strains.
- Maximum, dense healthy bud growth!

Here's a link to their feeding calculator but I wouldn't start higher than half dose at the beginning.
