@ceys111, I've been doing anywhere from 6.2-6.7 trying to get a slightly different PH every watering. I'll try to stick closer to 6.2 to see if that helps, thanks!

I learnt a few weeks ago that coco should be preconditioned using cal mag. Otherwise it will release phosphorus and sodium during your grow, as you add cal mag while watering. This can mess with the nutes balance in the growing medium also the cal mag you add is locked in to the coir until its saturated.
This is Internet science that I found somewhere
