Autopots and coco can kick butt. My first indoor grow in my 2x4 was this combo in the xl fabric pots rolled down to ~3 gallons, and I got over 300 grams from three plants, two of which were small genetics (Mephisto 24C). Had I managed to dial the nutes better, I likely would have done even better. If I go back to salt nutes, coco/perlite will be my plan unless I decide not to go to soilless peat based on Bugbee's mix.
If you go with salt nutes and coco in your next grow, you might want to consider a regular top water/mini flush once a week or so once the plants are on the reservoir. In theory, this should avoid mischief with salt buildup and consequent nute imbalance or lockout. Salt buildup has come up regularly for me, and even the gurus run into it once in a while. I haven't regular top watering to deal with this yet, but may if I go back to salts.
Good luck with the rest of your grow, and all the future ones.
