Hi max,
how much and how often do you water? What size holes do you have in it? Have you elevated your buckets so air flows under? Thought about increasing the hole size? Roots like air so maybe drill hole all the way around the bucket up 3/4 the way to the top. Maybe none of the above, maybe all of the above. Temperature and humidity can be a factor to
hope this helps

Little plants and big pots are difficult to water correctly don't know what size plants are in your pots but if they're real small you need not water that much possibly even transplanting to smaller pot might help good luck

The biggest factor would be the size of your plant. A fast growing, large plant would drink MUCH more than a tiny one which doesn't have much roots yet.
That being said, Promix especially if you added perlite should drain FAST. Actually too fast for my taste almost, especially when you grow with it outdoors in heat.
