Seedleranswered grow question 3mo ago waaaaaaaaaaaaay too much fertilizer. You see how the tips of your leafs point downwards? Also the leaves look super dark green which also indicates nutrient toxicity. I only Measure E.C. so i don't know how much that is, but it's obsl too much. Lower the nutrients, maybe try 1/2 strength and look how it develops
Good luck on that!
