beginning week 7...vertical growth has stopped...I have 5 bulbs total on the plant..two on top and three on side...4 are 2700k and one is 6500k...the ph in the attached picture is from a gallon feeding jug with the nutes already added....looks around 6.5...with nutes added ppm is 237....the base water with out nutes is 82 ppm...nutes per gallon are tablespoon big bloom and 1/2 teaspoon tiger bloom..both about 1/4 strength from recommended dose.....well water but pretty good deep artesian well so thats why it has pretty low ppm...I have some spotting on lower leaves not on top two thirds..so deficiency of macro nutrients like npk or mg?..over all plant does not look so bad...but wondering if maybe ph is preventing nute delivery or if i am not giving enough nutes maybe?...thanks for your help.
