600hps coco or soil?

Hi. currently have og kush clones (non auto), 600hps light, 19ft² of space(6-8 strains),scrog, have floraseries nutrients (would like to use them). thinking between soil and coco or combination of both.
what do you suggest? i just found nutrient charts on web for autoflower strains. how much dosage in periods?pls help me..thx

Unless your building some sort of organic super soil I would pick one or the other and not mix coco and soil.
I would go for coco, but then so would everyone that uses coco already. Any soil guy will say go with soil.
I find coco to be easy for a noob, less chance of over watering, you can feed more often. With coco what your plants have available is what you put in. You have full control and can correct things quickly.
A soil guy will say soil is more forgiving.
Either will work well.

Here's a link to feed charts

You can use the Lucas formula with those nutrients ( I think) Which seems the popular choice with the 3 part GH nutes

coco will give you good results and quicker growth than soil, its my medium of choice. that being said, if you're going for quality over speed, theres a lot to be said for soil. you can get a higher brix count in soil, and with the proper care, you can grow awesome frost covered thc bombs, of course you can get nearly the same results in coco, in about 2/3s the time, so thats what you have to ask yourself, is a 5 to 10% quality increase worth 3 or 4 weeks more growing time?

I get faster results with coco over soil. But i love my dwc.

Soil already has nutes. Coco only drinks what you feed. So id say coco so you know exactly what its feeding.

Thx for replies and help.before i put coco in pots, must i flush it? Or i make mix (from charts)for 1 week of veg.how i prepare first medium

i like to wash my coco, they're supposed to do it before you get it, but i don't trust them, i've found big salt crystals in cheaper brands (its made from coconut husks, that they pile up on beaches till they're ready to process them, so they can get a lot of salt water washing over them) coco will also absorb magnesium, so its a good idea to charge them with some cal-mag when your'e rehydrating it. again, some of the better companies do this, but a lot don't.
so basically, get a container, rehydrate your coco, then run about ten times the volume of coco worth of water through it, and i like to manually dig a little and see if i feel any big chunks of anything while im doing it, then when its pretty well drained, add a good dose of cal-mag, let that soak in, then use it

Cant go wrong with washing it and giving a dose of cal mag with new coco.
If you buy hydrated out of the bag it should be free of the high levels of sodium and potassium which it is naturally full of. That's why you should was the shit out of dehydrated block coco. Hydrated it should be already buffered too. Which means they have treated it with Calcium to replace some of the potassium. The Calcium and magnesium are attracted to the negative ions in the coir, so they latch on. That's why in new coco you can get a Cal or Mag Deficiency.

Since you already have hydroponic nutrients, I'd say go for coco. I grow in soil, but I'm organic and build my own soil. I find organics really fun.
