I’ve heard great things about those QB lights! Fellow noob here, but I wonder if maybe they’re a little too close? Maybe notch them up a few inches?
I didn’t realize you were in your second week. You can go at a quarter or half strength off the flora nova schedule, just keep everything in proportion. So if full strength calmag is 3mL, cut that in half as well.
I hope you love the DWC. You can grow monsters. They are calmag hogs, especially under the LEDs. I aim for a pH of 5.8 as well. Here is a pic of my girls in the 4x4: a GG4 at 86 days on the left and 2 NLs at 56 days.
