Hi
@Verlido! Your plants look healthy so congrats, they are stretching a lot, that could be a sign of too much Nitrogen, or just a lack of direct light. However you should be very careful, since it's easier to solve a slight deficiency than to recover from a nutrient toxicity, so keep being attentive to your plants reactions and slow down on feedings whenever you see the first signs of a toxicity (burnt tips or dark green foliage). Hope this will help, keep us updated and happy growing! π
