Not too much, they are just doing their thing and growing.
There has been a couple of rainy days so i took the domes off since the outside air is already pretty humid (above 70%)
Applied a very small dose of power roots once (0.5ml/l) and the rest of the days i watered with plain water (ph regulated to 6.4/6.5).
No need for extra nutes since soil is already a light mix. Will start feeding probably on week four depending on how they look.
