Man you gotta speak in terms of english measurements for me.

I never grasped the metric system.

The only thing I read that would cause me concern is 2800 lumens of light.

Ideally you want 5000 - 7000 lumens oer sq. ft. for optimal plant values.

Lights! Fix the lights.

Nutes are rated in NPK ratios.

High 'N' during veg...depends on how long you intend to veg....you shouldnt need any nutes for at least 3 -4 weeks if your soil is good.

P-K is needed during flowering.

Light and easy on the nutes....once a week at most during flower.
