wow I didnt know that. I agree that the temps are too low, but never knew it would create lock out.There's no doubt then! Temps in the low 60s will lock out Phosphorus and Potassium causing heavy damage! And don't get me wrong FF is great soil. Also seedlings don't get that big in bad "hot" soil. I bet my ass temps are playing the main role at killing your gals!
Its both temps and them being thrown out into the weather without hardening they had 80 something in the straight sun and then dropping to what low 60's in the first few days.There's no doubt then!
