I would check your water levels daily for at least 1 week, sink your finger down into the mix and see how wet the mix is. If it's too wet midday after you have watered I would say there is too much water in the mix. Then you could drill more holes to allow more water to drain out.

The goal is to have your mix drain well but to also hold enough water to allow the roots to drink when they need to. If the roots sit in too much water they will be drowned and not get the oxygen they need. Also, having too much water consistently draining from your buckets means your nutrients will wash out of them.

The next time I would put a couple inches of rock in the bottom, cover with a weed cloth and then fill with mix. This would allow the mix to drink water when it needed it and you would have less sitting in the mix while the excess drains out of the holes you drilled in the sides.

I am no expert here but this is what I would do.
