i've just got it in hortico potting mix with perlite. have been watering with ph about 6.7 i think.
Shit my bad, looked like a coco mix bud... OK, here's what I want you to do and please trust me on this one. You need to come see the Wizard. I really know my shit in coco, but I am learning from the best of the best when it comes to soil. GandalfdaGreen and Rrog will have your girl looking perfect, in 3 days MAX.

Swing past this thread, show this picture and bring the following details: Soil Mix, Nutes given up to this point at what dose, your pH, what additives you have added to the soil, approximate moisture levels, grow box temps, and absolutely any other detail you can think of. Gandalf should be popping past in the next few hours so get on it. Trust me bro. Many plants have gotten the ICU on that thread. 3 days MAX. She will look wonderful.
