You are far from messing them up. Just watch your watering and feeding program and know that those plants are going to use a fair amount of nutrients from watever media you are in. By now you should be easing off any N and if needed supplement P/K, trace minerals..etc. Maintain proper PH for your method, If you are in organic, maybe add some molasses in there. But without knowing what your program is its best just to maintain the "basics" right? Your plants look good.
Oh yeah, when I water my bucket plants, I poke a few holes down about ten to 12 inches when I water. That seemd to help. my shorter pots I poke about 6-8in.
