@Green09Ranger, for seedling feeding I use a 1 ml syringe, that way I can dose the correct dosage even for small watering amounts

@Athos, thanks I’ll check when I get back to my home computer

@Jeff123fish, Check the 6th picture, the one called "Holly mary jane (unknown one) 30/03", open the picture in a new tab and zoom in, check specially close to the tip of the leaves,

I can’t see the spots that you are describing in any of your pictures. Can you add one?
