Nutrient/Food Question?

Alright, here's how it goes. I haven't created a journal, don't know if I really plan on it but I do have a few questions that I am sure someone has advice on.
Currently I have 5 girls 1 in question. 4 of them are clones:
-Bertha (girl)
-WW (girl)
-2 Permafrost (girl)
-Dank Bagseed #1 (girl)
-Dank Bagssed #2 (hmmm...)

Well it is about time for these girls to flower and up until now I have been giving them basic food such as Schultz 10-15-10. I have a blossom booster on hand but is over a year old and would like to pick up something new, what would be recommended and what ones should I give them during flowering.
Any advice is appreicated, thanks.
Ya dIg?

I grow in soil and use really good nutes that have been used on alot of the past C Cup entries. HESI Bloom Complex(flower), HESI Phosphorus Plus(extra during flower), and HESI TNT Complex(veg.).......ive seen great results compared with miracle grow. Im no hesi fanboy....i just think its the best i can get from where i live
