Urggh just noticed my new seedling the first true leafs look dry or burnt or bit of both, i wouldnt have thought it would be nute burn so i have splashed little bit of water on her and placed propogator top over her, fingers crossed
Edit: More so think it was struggling with cross wing from fan, just need to check more regular, didnt bother check this morning when fed others
2nd edit: Infact sounds like some kind of tip abortion, when water is left on leaves over night nd temps drop, causing plant to grow ethylene, which aborts that new growth
