Thought I'd follow along. Indeed coco is different then soil. Cvh gave you some good advice. But lately I've been reading to ph to 6 or even 6.2 so anywhere around 6 should be good.
In plants starting out...even in coco, a little drying helps to get good root growth. Once in final pot with roots established...you can water daily or even multiple times a day...never drying. IMO
