Looks like we have the same sized tent... good idea to let one plant flourish in there! I'll be growing some mango smile later this year - great genetics! Good luck
@PositiveVibes,Thanks - I learned the hard way. My first two indoor grows, last year, I tried packing four plants in that little tent and it was so crowded in there, I could hardly get the watering can in far enough to water. That was before I learned how to prune 😆
I’m thinking maybe your PH was off . I can’t make out what kind of soil you’re using . I’m grow in coco and my ppm is around 1200 for my mango. Week 10 and not one yellow leaf ! Advanced Nutrients is the way to go !
