Hi, 
First of all, looked like you took clones of a sick or unhealthy plant = never a good start. 
Secondly your plant in question is too big for the container it's growing in. 
I also see signs of over-watering,(drooping down/floppy leaves.
I can't see any mention of nutrients or feed anywhere so hard to comment there but looks too be lack of nitrogen and maybe calcium/ magnesium, there's are the most commonly required nutrients at this stage. 
Are you checking the phone of your water? Make sure it's on the correct zone 5.5-6.5 (I prefer the 6/6.6 range)
The issue is most likely container too small therefore lack of root system and over watering.
