These seedlings were started in my standard mix- WruckMix with the peat moss mixed 50/50 with a potting soil.
They immediately started yellowing and I suspected overwatering. But removing the water didn’t help.
Since these are experiments for a window sill winter grow, they weren’t critical, so I decided to see if I could push them with full strength fertilizer.
The first picture is how they appeared at the start. (Aug 27)
The second picture (today: Sept.4), the larger row of 3 seedlings were given 5ml each of full strength triple-20 with a 1/4tsp Epsom salts per gallon after the picture was taken. (The black lines on the tray were the mark for the heavy fertilized seedlings- it was just dropped in on top of the soil with a syringe.)
Now the full tray is getting full strength, rather than the 1/10 strength I normally use.
