I was a little reticent to give it a full soak, but made sure to give it the 2x watering, getting all the soil as wet as possible then letting it drain through the bottom of the pot, then repeating the process about 15 mins later. There's a skewer in there too, so I can monitor moisture levels.
Other than that, I'm feeling a lot more confident that I'm not going to destroy the little fella now. Be interesting to see what he does over the summer.
Thanks again for all the help,
I would think it's a case of watering too much now. The gnats would be an indication of soil staying wet for too long. did you look up the chopstick method? It really would be worth it...
