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!

PPFDaddy Week 2 of veg and the bad luck already kicked in. As you can see in the pics, two out of the five plants decided to give me trouble right away. I kept a fifth seedling as a "backup" since this is my first grow in coco, and thank God I did. All the plants were getting the exact same feed, same EC, same pH, same temps and VPD, so the only explanation I can think of is that a few drops of feed must have fallen on the leaves during watering and burned them. There's really no other reason, because the other girls are doing great under the same conditions. I removed the one that was completely gone and replaced it with my backup seedling (another Hyperion F1). So now the lineup switched from mostly Runtz Auto to two Runtz Auto and two Hyperion F1. The backup girl is growing a bit slower, probably just transplant shock, but she's pushing through. For now the rest of the plants look fine and are growing at a steady pace. I'll keep the environmental parameters in range as much as my gear allows and monitor EC and pH both in and out every day. Thanks for stopping by and may your tents stay green and happy! #CocoGrow #AutoflowerGrow #RuntzAuto #HyperionF1 #CocoLife #GrowDiariesCommunity #CocoForTheWin #BarneysFarm #RoyalQueenSeeds #GrowersSupportGrowers

PPFDaddy Week 3 of veg and the ride continues. The Runtz batch really tested my patience this round: two plants popped looking all twisted, and one was so hopeless I had to toss it. All parameters have been on point every day, so I'm honestly starting to think this pack was just cursed. On the bright side, the Hyperion F1 girls are absolutely carrying the team. Two of them are growing fast with huge, healthy leaves, and even the backup Hyperion (used to replace the dead Runtz) is slowly catching up after the transplant stress. Compared to my old soil run where Hyperion stayed tiny for weeks, coco is clearly another planet. I also installed the Spider Farmer drip system and swapped the stock drippers for Halo-style rings. They're not perfect, but way better than the originals-without paying 25€ for a plastic circle. That's it for now. Hopefully the Runtz stop trolling me and everything smooths out from here. Happy growing everyone!

PPFDaddy These autos are absolutely ripping, especially Hyperion F1 from RQS. Explosive growth and crazy root activity. I had to increase drip volumes day after day as they kept drinking more, reaching an 8L tank today with almost no runoff. They're feeding hard and loving it. The Runtz that struggled early made a full comeback this week and is now stacking internodes fast. pH locked at 5.8, EC around 1.5, runoff EC always lower than input, so the plants are clearly pushing. Space is becoming the next challenge. This tent is turning into a jungle. I'll likely add a SCROG net and leave the pots exactly where they are, moving them would be a nightmare. With an automatic drainage system already in place, it should stay manageable as long as the girls stay happy. Coco + high-frequency drip is delivering the strongest auto results I've ever had so far. On to week 4.
