TLDR; My plants are dying. Pics below. Please help! We have 3 OG Skywalker plants. They're all in one grow tent (5x5x7) so they get the same lighting, air quality, temp, etc. They all get the same water and nutrient mixes (from the same container and batch). Our first grow did great but these ones are not happy AT ALL. I'm afraid they're getting to the point of no return. Pics are linked below with each plant numbered. Plant one is WAY smaller than the other two and practically dead. No idea why. Plant 3 is okay (not doing great but not dying either lol). Plant 2 is not doing good but is way bigger and healthier than plant 1. Any advice on how to salvage these poor girls? Any help is GREATLY appreciated!
