bloom booster

ive been in 12/12 for a week now and i need to water but i dont know if i should use nutes or bloom booster. when should i start using bloom booster? and what is an easily available but noticably effective bloom booster (i say easily available cause its a small town closest city has one small hydro shop)

anyone know how to make an effective organic bloom booster??

I just used bloom booster...10-60-10 works great...just dont add alot or it will burn the pistles on the plant..i also add fern nutes for better green leaves..ive noticed my plant loves alot of oxagen..

I use GH florabloom at half strength with about a quarter dose of KoolBloom at about 4 weeks or around half of the budding time
I think full dose of koolbloom is best around the fifth or sixth week so I gradually GRADUALLY raise it during the first week or two. Keeping your bloom ferts at half dose is best. The fourth week and fifth week get this Full Dose then I gradually lower it till the flush

these are at 4 weeks with the second dose
