Cannot address the autoflower part, but me thinks you are in Miracle Grow and the stuff is burning the plants. Sure looks that way to me. I suggest you fill out the troubleshooting form if this is not the case. Miracle Grow contains a lot of nutrients that release each time you water which is too much for many sub-species of cannabis.
WashougalWonder Reviewed by WashougalWonder on . I need help! First time grower..think im making mistakes!! I'm a first time grower and fear that i am making mistakes.I have 3 plants growing right now, the seeds (feminized, blueberry/diavolo hybrid called La Diva) have germinated and have now grown to little plants, which is where the problem comes in, one of the plants is thriving and is about 6 inches in height while another one, is only about 3 inches in height but its leaves seem to be "fatter", aside from the height issue, it also seems to be doing well, on to the third plant, the biggest issue, Rating: 5
