labifleanswered grow question 6y ago Hey gardener! If your leaves are pale, it means you're lacking nitrogen in the soil or in your feeding, so start increasing the doses of your growth fertilizer. You should still check your pH and EC, especially the EC, which tells you how much fertilizer you're putting in the water, so you can know if you're adding too much or not enough. For example, if you had one, you could have figured that out without asking a question. Good luck, bella ciao!
