Just consistent advice from 2 separate growers and I only feed 2 on the smaller ones but they're in coco coir so I water until runoff everytime. In my experience thus far, I did experience over watering in the beginning but pj diaz I believe his name is suggested bc of the nute deficiency I had bc my pH my lux my ppm/EC we're all off causing the issues I was having, to flush once then continue feeding as regular. 2 times per day for smaller plants and 3 for the larger ones to allow them fresh water and less salt retention. They're being grown in coco coir, not soil this the frequent feedings. I also feed with every watering. I have half strength bottles and whole strength using dyna gro grow and bloom nute. Did use in combo with cal mag but I ended up dropping it after the cal mag deficiency resolved. And the dyna gro has sufficient cal mag.
