i saw the feeding chart but that is for general hydroponic and I’m using Roots organic I no you said something about the cal mag supplement.. I just know that chart is different from roots organicI would wait at least a week to give nutrients. You will want cal mag suppliment and give at full strength for first few weeks and add through grow.I would start 1/4 strength base nutrients after 7 days its popped. Ill post a chart you can follow for ph and ppm targets it is a pretty accurate chart to follow.
