Genetics or Phosphorous deficiency? Second Grow here. Strain is "Blue WHale" (Blue Dream x OG Kush). Half way through week 6 since flip. Grown in Happy frog, then Ocean Forest once transplanted to bigger pot prior to flower. 2x2x5.5 tent. 110W LED . RUnning out of room in the tent. Light is about 10 inches from tallest bud. Water 1 gallon everyotherday. Water PH 6.8-7.1. 2.5 teaspoons foxfarm bigbloom and 1 teaspoon demeters revenge calcium everyother watering.
Cant find much on the genetics of this particular strain. I just want to make sure this is not a phosphorous defeciency and hopefully its just genetics. I did go quite heavy on the fan leaf defoliation this go around. Leaves are starting to turn purple starting from the outside in. It is starting only at the top of the plant at the moment. Particularly near the middle of where my light is. Im wondering if maybe the heavy fan leaf defoliation and the use of calcium is making the plant try and absorb more nutrients than it has because of the lack of fan leaves. Really hope this is genetics as I want some juicy purple nugs. But I want them to be purple because of genetics, not a deficiency. If it is a deficiency, how should I combat this?IMG_6248.jpegIMG_6247.jpegIMG_6246.jpeg

Not sure if demeters calcium is just a cal mag supplement, but I’m surprised 2.5tsp of Big Bloom has been enough until now.
Tiger Bloom is the bloom nute, not to mention Big Bloom is measured out in tbsp, but whatever you’re doing they look good
