Hi, First time grower here, inherited some stuff from my bud. He grew organically with a mixture called super soil. The pictures attached are of a WW. Initially when it was a seedling, I grew it in a mixture of FF light warrior and FF ocean forest. When the WW was ready for transplant, which was this past weekend, we put it in the super soil. The brown spots were already forming before then. The super soil contains: FF Ocean Forest Happy Frog Light Warrior Perlite Dolomite Lime EWC It is sitting under a 400W HPS. Humidity is at a steady 60% and temp sits around 78-80 F. I PH tested my water (which I let sit in a 5 gal bucket for 24 hrs to let chlorine dissipate) and it is testing around 4.7 PH -- though the water district is reporting between 7 and 8 PH in their annual report. I have a feeling my PH strips are crappy. Any help would be great! Thank you!
