Hello. Im doing my 4th grow. All my grows have consisted of same strain and nutes. Im running: 1000 HPS Bio Thrive Bloom and Bio Bud as directed Temps 75 day/night and Hum 45% day/night Ocean Forest/Pro Mix 70/30 cut Im on day 40 of a 60 day flower. Ive grown this strain Blueberry/Trainwreck in the past under exact same conditions. Recenctly in this grow Ive noticed yellowing of the leaves coming directly out of the top buds. Ive never seen this before. I realize larger fan leaves yellow as nitrogen is used up but this is different. Some of the leaves are even turning white?? Its seems the yellow/white are starting on the inner leaf and moving out, the tips are affected also. Possible nutrient def or nutrient burn? Thanks in advance Ill attach best picture I can.....
