Zkittlez Soil VS Hydro

Well I got 2 struggling seedings in the same grow bag, while P2 is thriving in another grow bag of same contents. They are the same strain, zSkittlez but 2 different batches. The test run I did was the same as P1 which doesnt seem to be as tolerant to the heat. Heat is the big thing i am watching as the temperature continues to rise; tent reaching 90F and water temp was 82. Hydro plants are actually as expected, these guys moved right along just like the tester did. I am trying to shave a week or so off the seedling time and these guys should be all caught up in 2 weeks. Then we can start looking at Flowering.
