Co2 during veg with LEDs

[ilovesluts420]

So I was wondering what ppm I should have my co2 set for during veg and flower. I’m running coco under gavita 1700e’s. I was told that I should run the co2 a bit lower under leds bc if it’s too high it can cause deficiencies.

I would only use it in flowering, between 800 to 1300 ppm depending on the size of the grow. .

Sure C02 is fine at any stage of vegative growth if you need faster growth.

In veg 600 ppm is a nice number.

I have never heard of C02 causing deficiencies.
