I’m trying a few plants on semi-hydro, hoping to rejuvenate them - after 2 weeks, I noticed white precipitate forming on the topmost Leca balls. I noticed new roots starting to grow so the plant seems to be adapting, but wanted to get feedback on what’s happening and what I should be doing differently. I’m watering with 1/8th tsp/gallon MSU K-lite with each watering, letting it flow out of the side holes, put in a half inch or so from the bottom. Are the salts accumulating in the topmost layer as liquid is pulled up as it’s evaporating in just 2 weeks? Thanks!
