Can't get your pics to load on my phone so I'll cover the basics if you think it might be bugs first off is there anything flying around? If no check the underside of leaves first place to look use a magnifying glass if you still see nothing how often and how much are you feeding your using coco so you have 0 nutrients in your medium to start with also since it's coco did you do a pre flush to remove and salt build ups that could be contained within the coco lastly is your environment air tight you could possibly have outside contaminants coming in contact with your plants

Ph is a bit on the high side for coco,6.2 should be your upper limit,but you will lock out some micros at that PH.If you are hand feeding Its important you vary the ph of your feeds from 5.6-6.2.This will make sure your plant is getting what it needs.The spots on the leaves look like calcium deficiency,but that can be deceiving.I think your problem could be a manganese deficiency brought on by high PH,if youve been feeding at 6.3 the whole time.Manganese is locked out in soiless above 5.8.for example and can give the symptoms you are showing me.I dont know what you are feeding but I hope it contains all the nessesary micros.Your next feed ph to 5.6 to see if it stops the progression.The damaged leaves probably wont recover.
Also be aware that due to the cation exchange capacity of coco coir,you can develop calcium and magnesium problems,so its a good idea to have a targeted solution on hand,like botanicares cal-mag for example.Its one of the things that annoy me about coco.
