What's the EPSOM means?

Look up epsom salt. Add 1/5 tbs per gallon of water.

Your EC is awfully high. Your runoff is crazy high.

You shouldn't just start adding things. You never said what nutrients you are feeding or what kind of water you are using. Those are important details.

In 1 week I use RO water
Day 1 Floraflex B1 ,B2, , Cal mag, EC2.5 Ph6
Day 2- ---
Day 3 Floraflex B1 ,B2, Bulky B EC2 Ph6
Day 4 ---
day 5- Floraflex B1 ,B2 ,Terpinator, Power si bloom EC2 Ph6
Day 6 ---
Day 7 Floraflex B1 ,B2 EC2 Ph6

Runoff EC6 Ph6 I have flushed once, Nowaday runoff EC2.2 Ph6

I'd drop all of those additives and just use the B1 and B2 at no higher than 2.0 EC.

I never reach over 1.2EC and grow large plants DTW and hempy. Way too much.

You could turn down that CO2 as well.. you're inefficient at anything over 1400-1500ppm at this stage.

I recently watched an interview of the Jungle boys head grower and owner, Ivan, say he never takes CO2 higher than 1500 ppm. CO2 can be toxic if it's too high. I don't use CO2, I do know that 1200 ppfd is too high without it though.
