GrowerOGanswered grow question 10 hours ago Hello mates, i advice you to be carefull with the organic product, all the matter you give that the plant don't be able to absorb, will stay in the soil. if you conitnue to feed every other day you will risk an overfeeding. Anyway you can give the water with the nutrient the last day before you leave and they will be fine. If you are very worry about you could give water with the saucer system, you put the water in the saucer and let it absord from there.
Good luck and happy journey!
