I mix my plant soil with regular potting soil and perlite but i noticed the top of the soil gets very ugly fast with the perlite. Dry and just looks unhealthy lol. Should i start to just bottom water my plants going forward to avoid this or is it normal? Its almost like when i plant them there isnt too much perlite on the top soil but when time goes on its like all the perlite goes to the top haha
