Hello everyone. First time grower here looking to hopefully get some help with my watering and feeding in coco. Using the Canna coco line with canna coco using tap water phed down to 6.0 or so. have read people use half RO water and half tap, but i don't have the resoueces for ro water. At least not one readily affordable. So far only used rhizotonic for the youngens out of the dome, but fixing to start up on a and b, but not sure if my water will lock up nutes or what not. have gotten a hold of some humboldt equilibrium and was wondering if this will solve my problem. Any thoughts anyone?Any help would be much appreciated.
