Proper feeding for 12/12 from seed

[nicedates1]

I am growing 12/12 from seed using GH nutes. I am wondering whether I should start seeds with a 3-2-1 grow formula and switch later to a 3-2-1 bloom formula.

Also, what would be good PPM readings from from seedling to mature plant?

Thanks

12/12 from seed will still have a veg stage. It won't start flowering till it's ready.

Start with veg and when pistils come out switch to bloom.

Ppm seedling to flower? Somewhere between 500 and 1500 don't start nutes till the true leaves come out.

Veg your plants under 18 hours of light, feed them an all purpose grow food as they need it.

plants don't grow much in the dark.
