ok so I took some pics.. they are looking a little better.... right now they are all getting week 1 nutes... kind of confused.... do i need to always alternate feed, water, feed etc. or could i do feed, water, feed, feed water etc.

pics 1 and 2 are just of 4 of them
pic 3 is of the little yellow leaves on one at the bottom
pic 4 shows the biggest one and another the biggest was really overwatered at the beginning
pic 5 is of the biggest plants new growth in between so i am not as worried bc it looks a little better
