Hello. After turning off the light, before going to bed, I sprayed the plants with a solution of Delta Nueve (4ml/l) + Kanna boost (2ml/l). By cutting off the leaves we have deprived the plant of sugar, Canna Boost has what the plant needs at the moment. Before that, the plants were fed under the root. The plant is healthy, does not show any ailments, and therefore will not notice damage if we pay attention.
