Thanks for stopping in Xcrispi. Dusto, I feed every day and with the run off I haven't had any defs or salt build ups, but with moms in coco I would prob nute every other watering with a low mixture. For moms I still go with soil because with something like Shultz all purpose fert you can just keep moms in a 3 to 5 gal pot for a year and feed with plane PH water and the plant should do fine and it is pretty low maintenance. Just try to get a little run off now and then and something like Clearex to flush will be sufficient if any build ups occur throughout the year.
Adieu
