Hey guys I'm a first time grower I have a GG4 in Coco I use the professors A B nutrients she is under a 100w ProGro Halo LED and noticed the leaves were beginning to turn purple on the tips of the upper leaves and then they turned into a deeper brown kind of stain. Covid has prevented me from getting a PH tester as of yet could this be an issue? cheers guys ![15990162210476902310677483938405.jpg](/data/attachments/3773/3773809-7940085481432d6e9f6dd27b0842256d.jpg)
