Wedding Cake Auto First Grow

I've noticed these guys drink a lot more water and I'm going to have to up each one to probably 3L of water per every 2 days. I've increased fertilizing from every 3rd watering to every 2nd on Day 50 because it looked like many of the leaves were showing signs of deficiencies. I hope I read the signs properly but the plants have not got worse and look like they are showing improvements I think. I pulled out my DSLR to get some better pictures as my cell phone just does a meh job.
