spots

Ok so i have a 10 day old plant who's third fingers are out but not matured, i see small brown dots located on the outside fingers but not on the center finger .. ive had a little bit of a problem with water and heat and thus have been having to water in small amounts everyday to keep from curling slightly, anyways.. any idea on what those brown marks could be from ?

you over watered,add wood ashes to water till it looks muddy,then change the ph from 10 to 6.5 water plants with this and a mild dose of ferts in the same water,wait 6 days for results
