Thanks for stopping by and checking my thread out.
Coco makes up the majority of my growing medium. I use 60% coco, 20% sphagnum peat, and 20% perlite. I run 5k flower watts and they are all 600's. I run one 600 over each 3x3 botanicare tray. I use drip rings and run DTW. The girls are 10 days into 12/12. I'll try and post weekly updates.
Day 23 12/12 Pics are Purple Kush, 3rd Coast Sour Diesel, and some Cookies Kush. Flower room 2.
I normally don't let them get this big. I was given some clones that were weeks ahead of the ones I took.

It's interesting to me that you're using peat in the substrate mix.
I run peat in my coco for a couple reasons. Peat holds more water and air then coco does. It's better for microbial life. Peat does take a bit longer to saturate then coir but coir dries out quicker then peat. Combining the peat helps the coco not dry out as quick which can cause a nutrient imbalance if the coco dries out. Coco coir's pH out of the bag is between 5.9-6.5. Adding peat helps me get the coir in my target pH range between 5.8-6.1 depending on veg or flower. I feel peat helps the coir become less finicky in regards to calcium, magnesium, and potassium. I can still water my medium multiple times a day but with the peat added I don't need as much water.
