Help?? Yellowing dry soil

Day 23 its my white widow yesterday it was prefect, only differance is i did add fox farm to it did 2.5 ml to the gallon since it was the first time and after its 6 hours off it came out like this and i had feed yesterday and its drier then the others

It's all good... The cotyledons have been leached of their nutes, this is normal as the plant switches over to start taking nutes from the soil. Adding soil was the right thing to do, now just give it a little water, not a LOT. Just a little so that a little bit of water comes out of the bottom of the cup and then stop.

This one i gently touched and it fell of the stem And these are all my clones only thing i did was give them nutrients and they did this what can i do wat can it be

dude your not reading your soil bag it has feed in it for your plant. to grow from you will not need to feed them till week 4-6 of flowering depends on how often you water you plants.
