I did email you, you responded. I told You I got my order and was shorted. 2 months ago and you never tried to make it right. I guess it is ok I got a partial order.
only thing I can come up with is they are not fully cure (which i doubt, cause it would still get u ripped). Is that you harvested too soon or you smoke way too much.
You will need to figure out what type of hydo you want to do and just do it. I would recommend a dwc set up. Air pump a ph meter and some air stones . You will be on your way.
Read the bottle, start with 1/4 and work your way up. 400 ppm for seedlings and up 1700ppm during flowiring. Just depends on the strain and what it can handle.
