You do not have soil. Coco is not the same as soil. The mix you have is coco and hydrocorn (clay pebbles), it is much more of a hydroponic medium as there is no nutrient provided by the medium and it will drain pretty quickly. It does seem that you have done almost everything right on point as your plants look good, I honestly don't see the almost black leaves you speak of but that could be the HPS lighting. If you are seeing leaves that are too dark it is most likely a nitrogen toxicity, so back off any nutrients providing nitrogen to your plants.

last 2 weeks u flush /. Like pour water through them like 12L per pot , than turn off lights for 2 days leave fans on ,

ur leaves will die off as the buds will suck the nutrients out of em so don’t stress its the buds u need to worry about, make sure there healthy and still growing.

For those big ass bags you are gonna need a ton more at waters.

There is also a problem you will see. I take it you are watering where the stem is in the bag correct?

If your waterings look like this and you aren't flushing a ton of nutes through them and the orange areas are going to be a problem. Even if you are flushing a ton of nutes I have a feeling you are getting a ton of buildup in the orange areas are prob a good lack of water. You need to water almost the entire top of it. Specially with hydroton in the mix. Mix like that is 3-5 waterings a day if you had them in a normal size pot.

should I put holes in the corners of the bag and water all holes?

Yes at the very least. Good amount of runoff also in a big ass bag like that. Just to give you perspective. 18 plants in 1 gals will run me about a bag to a bag and a half of coco for all of them. They will drink about 40 gals of nutes in about 5 days in veg not even in flower.
