1st grow , did not expect this !

Since I need to get mind rite a lot everyday , I figured I would give it a try. 4 northern lights , 4 ak48 and 5 bag seed of great smoke.
6x6 walk in cooler room recycled for growing , 400w hps , 8 cfl - total 10,500 lumen , intake and exhaust fans , ph 6.3. , temp 75 , humidity 58-60 , Fox farm soil , Fox farm big bloom.
4 ak48's are auto and started showing flower 9/15/15 and 1 bag seed started flower 4 weeks ago. All 13 are in 12/12 as of a few days ago.
Should I be adding any additional nutes and if so what. Any input ?

Nice, any close ups on the flowers??

Btw you should be adding bloom nutes with your veg nutes once in flower, your girls will need different ratios of nutes in this stage

what nutes are you using now?

I have tiger and big bloom are they good ? And mix together per bottle ratio ? Any specific brands to use ?
The girls are asleep will post flower pics tomorrow. Thanks for any input.

read the directions on the nutrient bottle. theres a chart online too for foxfarms.

I used the Fox farm ocean soil with happy frog fruit flower fertilizer 5-8-4 and fix farm grow big 6-4-4, ( 3 tsp per gallon ) , all for veg...
When I started 12/12 I switched to Fox farm big bloom 0.01-0.3-0.7 (4 tbsp per gallon and I have top Fed some happy frog 5-8-4.
All has been done per content instructions.
Where I am confused is what you can mix and what you should mix in for weekly feedings. I rotate feedings , feed , water , feed , water etc..

So , I think I figured out a mix to use.
Will use the fox farm trio and follow chart schedule.
This is where I was not sure , I didn't understand you mix all three to the gallon of water. I ONLY did tiger bloom for veg and big bloom for flower , along with ff soil , perlite and happy frog.
I am correct ? Mix all three to a gallon of water ? Maybe a booster or will this do ?

The schedule for ff nutes trio is a mix of all three on week 5 for a couple feedings. The ff feed schedule is online. I'm using it now.
