It would probably help a bit. You'll still need to supplement cal and mg.

I heard the chlorine in tap water does more good than harm to a plant, correct me if im wrong. I just talked to my friend and he said that his plant is looking alot better and healthy. he uses tap water and sits it out a couple of days to evap some of the chlorine out so it minimizes salt buildup and he doesn't ph correct his water (his water is about a 8 and his shit is looking GOOD)

man.... coco already has a high dose of "P" people usually using coco think that they burn there plants cos of the nutrients; but really its the high dosage of P alive in coco coir + the nutrients which lockout the plant. I would say use soil its the best solution it buffers PH levels and feeds your plants with nutrients for 4 weeks +. I Would say trash these plants and start over.. cos u wont be getting large yields anyhow.

Also dont forget.. adding nutrients 2 water generally lowers the Ph..so your friend might have 8.0 water but when he adds nutrients it will fall to 7.-7.2

good point, but I thought coco was completely inert of nutrients.... correct me if I'm wrong
