second run of these autos . last run was outside grow-2 weeks to harvest... running 2 in 6 inch rockwool blocks and 2 in 3 gal coco/perlite mix. 3 are super healthy but one looks odd and off. looks like this baby got stressed somehow. everything was ran the same...any thoughts or help. hopefully she will correct herself. just fed lightly this morning w ph corrected water w ppm of 200. hope to wash out anything she didnt like running in a 4x2 tent w 315cmh. 4" hurricane fan w 16" c filter... more pics to come and want to be better updating the grow every other day or so. let's get this starter !!!!
