I am using biobizz light mix in 5gallon fabric pots and finding it doesn't drain well enough, my plants are already in flower so I can't just add more perlite. What can I do to help propper drainage without disturbing my plants?
You should just let them take the water u don't need more drainage. Your plants are all very happy so don't worry about drainage. U got 20 L pots the plant can't take all the water in 3 days they're too young. The roots need more time to fill the whole pot and in week 3 it's too early. So don't worry ur lady's looking good. 💪🏼
