I think I poisoned my plants. Or had the fan on to...

Yes u are poisoning your plant if using straight vinegar it's an acid and can be used as a weed killer. But too me they look good at week 5. Hope you have your answer. And great harvest 😁

Hi! You are overwatering learn by the weight of your pots when to water..never fails. Also don't add more nitrogen she's shoving slight overfeed signs. Give her couple of times just Ph'd water and re schedule your nutes. Try 1/3 or 1/2 of what the bottle says. Easier to go from there.. Takes much more to take care of overfed plant with flushing and all. Happy growing!

Hi @ChrisHans! Your pH is a bit high, almost alcaline, whereas you need it a bit acidic (roots tend to develop and handle nutrient intakes better in an slightly acidic soil) so I would start by adjusting every watering to the 6.2 pH sweet spot. The dark coloration tells us that your babies don't need no more Nitrogen, I bet your soil had enough nutrients for the first weeks but you added some more in your waterings. Give the soil a break, by applying only pH'd water until your plants start to ask for more. Pay attention to your container's weight and insert a finger in your soil before watering, this will help you to determine the required amount of water. Roots need to alternate between wet cycle and dry cycle to properly develop and expand, searching for water. Hope this will help, keep us updated and happy growing! 👊

Organic growers use apple vinegar to lower pH, nothing wrong with it. I checked your weekly updates. You've been over watering a lot and feeding too much too early. Flush the media and do not feed anything, let the soil feed the plant, only resume feeding when the plant shows the first signs of deficiency. By the way, dark green leaves are nothing to be amazed at, it's a sign of over feeding, too much nitrogen to be exact.
