PPFDaddy Week 0: here we go again. First run ever in coco and I'm both hyped and slightly stressed. Everyone keeps saying coco makes autos go full potential mode thanks to better root oxygen and faster nutrient uptake, so we'll see if it's true or if I end up crawling back to soil with my tail between my legs.
Germination: 3/4 Runtz popped just fine, the smallest seed decided it didn't feel like joining the party. I replaced it with a Hyperion F1 from RQS that I still had around, so now it's 3x Runtz plus 1x Hyperion in the same run. Hopefully they behave and don't turn this into chaos.
Wish me luck and feel free to drop advice.

PPFDaddy Week 1 in coco is done!
Started the seedlings under domes for the first couple of days in the bigger tent with the older girls, just to keep light intensity soft enough for that early, fragile stage. Once they opened up, I moved them into their dedicated tent.
I've been watering once a day with about 300ml at ~0.6 EC and pH 5.8. Parameters look on point for this stage, but the first issues already popped up-early chlorosis on the seedlings that sprouted first. Not sure why, since EC and pH have been stable. I suspect the tap water here is pretty hard and watering only once a day lets pH drift back up toward its natural 7.5-7.8 over time.
Starting Week 2 I'll water at least twice a day to keep pH more stable and avoid swings.
Added a SwitchBot for VPD/temps/humidity logging-super useful to see how things fluctuate through the day.
Beginner in coco here, so if anyone has tips, I'd appreciate them. Wish me luck!
