cool no worries, you will know when it needs nutrients as new growth will be a lot lighter and the bigger leaves will look lighter, this is then telling you the plant needs more N, but you can easily go another week to 10 days on the soil in the pot so id just water at least for the next week then see how it looks,

that powder feed system looks a good option, very hard to get wrong
anymore problems just give us a shout
