My 11 day old seedling is turning brown at the tips of the the single blade leaves that come out after the baby leaves not sure what it is. Please help!
Seems like magnesium lockout,not really nutrient burn. Nutrient burn occurs mostly on tips of new leaves. What pH are you watering with? Lockout occurs above 7 usually. Please tell me you are not using tap water.
When I leech I use a product called Clearex there is another good one for leeching called final flush. And yes it is a flushing agent that has complex carbos in it.
