ph- BLOM or GROW

[nbody]

im about o start my first grow and i have som questions about PH correction.

I have figured out that its mutch better to by a PH- soulution then to use lemon ore so?
the shop that im ordering frome have 2 different soulutions.

-ph-Bloom 1000ml Helps to reduce the pH-level of the nutrient solution during the blooming period. Contains 59% phosphoric acid.

AND

-pH-Grow 1000ml Helps to reduce the pH-level of the nutrient solution during the vegetative period. Contains 38% nitric acid.

Do i need these 2 ore just one of them?

i am going to use these nutrients to feed my plant.

Bio Bizz Rootjuice 250ml rooting stimulator
Bio Grow by Bio Bizz 1000ml fertilizer for the vegetative stage
Bio Bloom by Bio Bizz 1000ml fertilizer for the flowering stage
Alg-A-Mic by Bio Bizz 1000ml
TopMax by Bio Bizz 500ml for big buds
Pipette/Eye Dropper 10 ml / 0.1ml

got all that fore 54.95€ pretty nice price i think.

peace

I've always used the bloom stuff for both stages. Better to have P in veg, than N in flower.

Bloom is fine to use throughout. Nitric acid is much more toxic than phosphoric acid.
