Too much horse manure

is not good at all. These afghan have 30 days old. Soil too rich => no growth. After 15 days of no growth and yellow leaves, i flush the soil from the roots and put them in a nutritive bath with bubler. The green color is back, i just put them in normal soil. Do you think i will have more males because of the bad treatments?

How old is your manure ? It really needs to sit for at least a year and maybe 2 to be really good for the soil. Any earlier and its still pretty hot stuff.
