HELP. First time grower here. Planted 1/4 watered twice since then about 8oz each time. Anyone know why seedling leaves are drooping already. What do I keep humidity at? Ive read 60-70% but with inline fan on its drops to 58ish. With it off it sometimes jumps to 80s. Current lighting is 18/6 schedule at 50% about 24" above.
