New grow box and grow

Hi all :fist_right:

Just done a water change & on checking my nutes i noticed this & almost flipped as bottles 4 & 5 had crystisation @ the bottom & on the tubing :scream:!!
I am now using Green Planet Dual Fuel 1 & 2 & Pro Cal
Ended up mixing the last bit of grobo thinking that would be better & less of a shock :roll_eyes:
Looks like they dont mix well :face_with_raised_eyebrow: & Type of Crystallisation :thinking:??
All that i could do is clean out & refill she looks fine & still Flowering nicely :ok_hand::




Bottle Nยฐ5:

Bottle Nยฐ4:

Hope someone can answer my question & help me :sleeping:!:wink:!:seedling:!:seedling:!:seedling:!
