Nutrients etc.

Ok guys it has came time for me to order some goods for my babies. I have been using RO water and lets just say i can tell they need some CalMag bad. So i want to know how much do you need to add to RO water. i am trying to figure out how much i want to order at a time (quart or gallon. My babes are 10 days into flowering and have been recieving cactus juice. Should i change that up to something that is for MJ? Suggestions? Also any suggestions on some bud boosters?? Basically i am trying to find a great, full, all around diet for them, so suggest away...

5-10 ml per gallon is what they recomend. A quart will get you past your first grow. But really it depends on how much water you use each time you change the rez.

Thanks Zandor, I am leaning toward just getting the gallon as this will not be my only grow. What kinda nutes do you use during flowering? Bud Booster?

canna flores is good for flowering i use it and a bud booster is good too or canna pk 13 14 is just something ya add to the food
cheers all :)

I use organic's.
Budswel and Pure Blend pro bloom for soil.
And Fox farm big bud.
I switch back and forth with the budswel and big bloom.
Then for the last 2 weeks of feeding I only use the pure blend pro and big Bloom.
I also add Silicate and superthrive moderatly.

Soil is just as important as the nutes you use.
I am planning on trying Happy Frog.
I use Light Warrior for veg.
And Ocean Forest for my Moms.
