Do yourself a favour

Get a good bloom booster for your grow, really helps

Yes, yes it does. Especially if you use it properly.

What are some good bloom boosters? And what bloom phases can and cant you use it?

Sumthin for example: 1:3:2 or 10:30;20 npk. Me, at the moment I use 11:35:15. I increase dosage as needed. I only use this begining flower to mid flower.

bloom booster is PK aint it? For example ''I use plant magic PK bloom booster?'' :-/ It works a treat...

Yes it is. As a matter of fact all ferts have a npk rating. Bloom boosters specialize in the pk department. Pk is vital for the flowering stage. Always be sure to read on the back contents n make sure your boosters contains a little cal and mag. Very useful. What are the npk ratings on the booster you have?

Yep, you still want nitrogen. When I switch to flower I start using half dose veg/ half flower. Each feeding I give a little less veg and a little more flower until around week 6 or so I am in full flower nutrients. Others might disagree but I hit them until they tell me to stop. I keep upping the dose until my leaves show signs of too much, then I back off just a little.

Bloom boosters, flowering enhancers are great. A good start for a bloom booster is at about 21 days into flower till the end. At least that's what I use. Then the last 3 weeks a ripener is added to the soup.
