will young plants that have been stunted/stressed ever show normal growth?

i have small growth. plants are 1 month old and only 4-6" tall. they have plenty leaves tho, just minature like. they were over watered and put out into the heat too soon. 2 problems..overwatering cause the top soil(less) was crusty, then these high tempertures recently. i have since put the in 1 gallon pots and they are in the shade most of the day. when transplanting the pH was below 7. i am using a organic compost, molasses, super thrive, ph down corrected (below 7 [6.8]), and 50% of a 24-5-10 recipe. they have good root system already..i suppose from the super thrive. they were pale green when all the stress was going on but now they are dark green.
will they ever show big growth since being stunted so early?
