Here's a few pictures. I discovered that the 2 largest plants had grown some super healthy white roots into the trays unfortunately I had to remove them. I gave all 3 plants a trim below and thinned out some leaves up top.

Day 58.
These girls are drinking 30L of nutrient solution every 3.5 days. I'm feeding them an EC of 2.0 (background EC 0.5) @ pH 5.8.
I supercropped one of the plants to keep her canopy even.

Day 72 update.
The girls are now going through 30L of nutrient solution every 3 days. I'm feeding them an EC of 2.3 (background EC 0.5) @ pH 5.8. I've increased the amount of Magnesium there getting because the leaves were yellowing between the veins. The tops of the plants are a pale green colour, but I'm hoping they'll darken with more nutrients.

I've also increased the strength of my lighta from 250W to 320W. Hopefully it won't get too hot.

Day 80 update.

I've squeezed my COB lights into 150mm ducting and connected this to my extraction fan to form a makeshift cooltube. It's allowed me to increase the power of my cobs to a little over 50W each, whilst maintaining a max temp of app. 32°C. I'm now running a total of 420 cob watts

I'm now feeding them EC 2.8 (0.5 background) @pH 5.8. A lot of this is calcium and magnesium, but they're still asking more calcium, which you can see in the pictures.
