Hi
@Capshot! Considering you only gave water since day 1, we can exclude nutrient burn. Your issue is not related to a nutrient noxicity for sure. That being said, we are missing some useful informations to diagnose your plants: what's your watering routine, how much water do you give each week? What's the temperature of your water? What's your medium, it's written 'soil' but what's the brand and what's the NPK ratio in your medium bag? Do you measure/adjust the pH of your waterings? Have you ever tested your tap water with an EC-meter? If you did so, what's the EC of your tap-water? These symptoms make me think of 3 potential issues: 1/ your water might be too cold, this can lead to burnt tips or yellow tips, make sure your solution is neither too cold nor too hot, 20°C/68°F is a safe temperature for roots. 2/ your probably have a bad watering routine, you must follow a wet/dry cycle, where roots are never too dry nor flooded in water, they must search for water in order to expand so whenever you want to water, try to weigh the container, make sure it's light and not full of water, give a reasonable amount of water (15~20% of your container's volume) and watch it dry, even if it takes 3 days, soil must be almost dry before you water it again. 3/ Your pH could have been wrong for the entire vegetative stage, if you did not measure & adjust the pH of your water, you could have created some nutrient-lockout. Indeed, without the appropriate pH in the root-zone, plants cannot manage nutrient intakes, and start to show deficiencies. I highly recommend to invest in a pH-pen and some pH-down, unless your tap-water has already the perfect pH for soil (~6.2, you'd be very lucky!) this is a mandatory tool for a successful run. Hope this will help, keep us up-to-date and happy growing 👊
