Baby poop color after starting solids.

My baby girl ls 7 mnths 6 days old... Since last 20 days, I feed her ragi malt as breakfast at 9 to 10 a. m, later give her formula milk on demand and then homemade cerlac between 2 to 3 p. m.. Is this too much for her age? She is completely on formula milk..drinks around 500 to 600 ml formula after starting solids..i used to give Her banana but stopped since a week as she has cold..Her poop color is dark green at least once In a day and rest of the day it is yellow color.. Is it ok? Also sometimes her poop is a bit hard.. I give her 2 to 3 tbsp of water after solid feeds.. Is it enough or should it be increased.. Her weight is 6.6 kgs today.. Is that fine? Attaching image for reference.. Pls suggest
