Hi john, i quite like marigolds myself easy to grow and germinate. It my first year growing African marigolds, from what i have found on the internet i think i might of found out what it could be.
African marigolds are not tolerant of low pH soils.Low pH causes iron and/or manganese toxicity, which exhibits itself as brown to black speckling of the foliage .
Could be that i am not really sure, but they need potting on anyway so i try and get my hands on some peat free compost tomorrow.
I do have two other variety of marigold, a stripped one ( one in the background ) and some honeycomb i think. The honeycomb are nearly perfect all nearly exactly the same height them little beauty's
And before anyone asks yes all the plants are living in the house tonight there everywhere
